Upcoming action game Rise of the Tomb Raider is currently confirmed to launch in holiday 2015 only for Xbox 360 and Xbox One, but Sony executive Shuhei Yoshida is hopeful the game will come to PlayStation some day. While it certainly sounds like the game will be released for other platforms later on, speaking with Eurogamer at Gamescom, Yoshida acknowledged that this decision is not up to him.

“That question has to be asked to Square Enix and Microsoft,” Yoshida said. “I hope the game will come out eventually on PS4. But how can I tell?”

A week ago today during Gamescom, Microsoft announced that Rise of the Tomb Raider would be an Xbox-exclusive for holiday 2015. This phrasing left open the possibility that Microsoft’s deal with Square Enix was only for a timed-exclusive, and Microsoft has since confirmed that indeed Rise of the Tomb Raider’s Xbox exclusivity “has a duration.”

Rise of the Tomb Raider is a direct sequel to 2013’s Tomb Raider reboot, which was released on both Xbox and PlayStation platforms, as well as PC. Some Tomb Raider fans were upset when Microsoft announced the exclusivity deal last week for Rise of the Tomb Raider, and Yoshida says he didn’t have any inside knowledge about this deal going down.

“We didn’t anticipate something like this would happen,” he said. “How could we know?”

Yoshida also says he heard gamers’ opinions about the Tomb Raider exclusivity deal. “In general, there are lots of people who are angry, who emotionally reacted to the announcement,” he said. “Some people created an image saying negative things, like the end of Tomb Raider. It was a very emotional response.”

Microsoft and Rise of the Tomb Raider developer Crystal Dynamics maintain that the deal will help elevate the Tomb Raider franchise. The deal between Microsoft and Square Enix, according to Xbox boss Phil Spencer, is a win/win situation, and not an attack on PlayStation fans. Signing Rise of the Tomb Raider as an Xbox-exclusive for next year will also help Microsoft better compete with Sony’s 2015 game Uncharted 4: A Thief’s End, Spencer said at the time.
