The Microsoft and Square Enix deal that will see Rise of the Tomb Raider launch exclusively on Xbox "has a duration".
That's according to Xbox boss Phil Spencer, who also told Eurogamer that the title will be released on Xbox 360 as well as Xbox One next year.
On Tuesday, publisher Square Enix moved to explain why the game, "coming holiday 2015, is exclusively on Xbox".
A statement from Darrell Gallagher, head of product development and studios at Square Enix, appeared to suggest the sequel wouldn't be released on PC or PlayStation consoles, but Spencer's latest comments indicate that may not necessarily be the case.
"It's not because I'm trying to be a head fake on anybody," he said. "It's a deal between us and the partner. People ask me how much did we pay. There are certain things I'm just not going to talk about because it's a business deal between us and them. Obviously the deal does have a duration. I didn't buy the IP in perpetuity."
Spencer also referred to Xbox One launch games Dead Rising 3 and Ryse, both of which will be made available on PC this autumn, almost a year after they originally released on Microsoft's console.
"I get the reaction I see," Spencer said. "If I'm a PlayStation person all of a sudden I feel like, the franchise has gone. I didn't buy the IP. I didn't buy the studio. It's not mine. Where this thing will go over time, just like Dead Rising or Ryse, we'll see what happens with the game. I don't own every iteration of Tomb Raider.
"I don't own them building Tomb Raider on other platforms. I can't talk about the franchise that way. I can talk about the deal I have.
"What they do with the franchise in the long run is not mine," he added. "I don't control it. So all I can talk about is the deal I have. I don't know where else Tomb Raider goes."
