E3 2014 is now just days away. We’re expecting a bevy of announcements from Microsoft, Sony, and Nintendo, as well as third-party publishers like Ubisoft and Electronic Arts, which alone plans to make six announcements at the show. It promises to be a busy week in Los Angeles, but there’s already a considerable amount of buzz built up thanks to a slew of rumors about what we may see at the show.

We have rounded up some of these rumors and provided details below. We will continue to update this story as more rise to the surface, and please don’t hesitate to ping us to share rumors directly. For more on E3, check out GameSpot’s roundup of everything you need to know about this year’s show.

Make-Your-Own Mario Game for 3DS.

Nintendo Enthusiast has obtained an image from Nintendo’s booth on the E3 show floor that features an unannounced 3DS game called Mario Maker. Going off the picture alone, it looks like you’ll be able to create your own levels in the Mushroom Kingdom. Sounds fun! But is it real? We’ll find out next week.

NFC Figurines for Super Smash Bros.

Nintendo France said that the upcoming Super Smash Bros. is going to take advantage of the Wii U’s NFC capabilities. Pair that with the confirmation by Nintendo of more figurine details at E3 and you don’t have to stretch your imagination to put the two together. Will these miniatures involve unlockable characters? We’ll find out during the E3 Nintendo Direct.

Grand Theft Auto V comes to Current-gen

We’ve been waiting a long time for GTA 5 to come to PC (at this point it’s taken longer than the same port for GTA 4), but maybe part of the reason for the delay is that the game is also being optimized for current-gen consoles.

Rockstar has said that they plan on releasing an Xbox One/PS4 game this fiscal year. While that could be the recently renewed Agent, an update of one of the best-selling games of all time seems a little more likely at this point. But the bigger question: Will it be a timed exclusive for Sony or Microsoft?

Dance Central 4

While talking about the Xbox One price cut and removing Kinect from Xbox One with Microsoft’s Yusuf Medhi, he casually said, “Certainly some gamers are Kinect-focused, say Kinect Sports Rivals, Dance Central.” While it’s possible that he was referring to an Xbox 360 version of the game or the franchise in general…but it’s also possible he accidentally leaked an upcoming Dance Central reveal.

Neither Harmonix nor Microsoft responded to follow-ups about the game, but E3 may give a lot of gamers a reason to use their Kinect for more than voice commands.

More PlayStation 4 HD Remakes

A lot of rumors have leaked about current-gen remakes of the Halo games, but we’ve heard rumblings that Sony has their own HD reveals as well. We already know about The Last of Us for PS4 update, but you can expect a few more games to get a chance for more exposure. The most surprising rumor we’ve heard: some of the PS4 updates might come from the Vita.

New Mortal Kombat

Ed Boon has been teasing an announcement for the past few weeks, and while that’s set to fall on Monday (pre-E3), we’re guessing that the inevitable Mortal Kombat reveal will also make a big splash at E3.

Big Third-Party Xbox One Exclusive

An reliable source has confirmed that Microsoft is going to have at least one “big” third-party exclusive reveal during their stage show. We don’t know the exact game, but our source said the game is both something “unexpected” and “something people will be really excited about.”

Halo: The Master Chief Collection

Microsoft says the “journey” to Halo 5: Guardians (2015) will begin this year, but what could that mean? According to Engadget’s sources, Microsoft is bundling Halo: Combat Evolved, Halo 2, Halo 3, and Halo 4 in a special package for Xbox One called the Master Chief Collection. There’s no word on whether nor not Halo 3: ODST or Halo: Reach would also be included. Those are not “core” installments in the series, so we wouldn’t be surprised if they were left out.

Halo 2: Anniversary Edition

Rumors about an “Anniversary Edition” of Bungie’s classic FPS Halo 2 date back to January 2014 and refuse to die. The remastered version will reportedly include 1080p visuals and access to a beta for Halo 5: Guardians. This rumor is increasingly interesting when you consider the game was released in 2004, meaning this year marks the game’s tenth anniversary. Sounds like a good time to release an Anniversary Edition, no?

Call of Duty: Modern Warfare Collection for PS4 and Xbox One

Earlier this month, Reddit user GTA678 posted an image of a “Modern Warfare Collection,” which will reportedly bundle Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2, and Call of Duty: Modern Warfare 3 in a special package for PS4 and Xbox One. The games will all reportedly run in 1080p at 60fps, with new textures, lighting effects, and sounds. Rumor has it this bundle will launch November 25 and even contain exclusive content for this fall’s Call of Duty: Advanced Warfare.

Battlefield: Hardline (CONFIRMED)

That escalated quickly.

This isn’t much of a rumor any longer, as Electronic Arts this week confirmed that the game is indeed real and developed by Dead Space creator Visceral Games in conjunction with DICE. We’re still waiting on platform and release date details, but the developer’s VP took to Twitter today to say that a leaked trailer for the game is six months out of date, they’ll be showing the “real deal” at E3, likely during its E3 press conference on Monday, June 9.

Tune in and find out.

Project Beast for the PS4

Stemming from images posted on 4Chan and circulated on popular gaming forum NeoGAF, this is reportedly the working title for a new game from Demon’s Souls and Dark Souls studio From Software in conjunction with Sony Japan. Demon’s Souls creator Hidetaka Miyazaki–now president of From Software–worked on this year’s Dark Souls II only in a supervising role; he focused most of his attention on an unannounced mystery game. Is Project Beast this game? We may not have to wait much longer to find out.
