Microsoft recently put a five year lifespan on the 360's motion cam, Kinect, but Capcom's David Reeves reckons we'll be seeing the next generation of consoles much sooner.

The Capcom exec and ex-Sony man admitted he has no inside knowledge on PlayStation anymore, but feels that we would be seeing the PS4 and Xbox 720 within two to three years.

"Anything they can add to revive and pique interest in the games until we have another clash of the titans in two years time," Reeves told GI.biz when asked about Move and Kinect.

When asked to elaborate on his prediction he said: "Two to three years, I reckon so. I don't have any inside information. All the first-parties have got to be working on something.

"The tricky thing is when do you put a stake in the ground on technology? That's the problem," he continued.

"You can be waiting a few extra months to implement something, but you've got to set a date to go with a certain chip at a certain point otherwise you're going to miss the key milestones."

The immediate impact of both Kinect and Move is still yet to be seen. But if analysis suggesting that the purchase intent for both is 'relatively low' is accurate, Microsoft and Sony might have to do more to sustain the lifespan of their respective boxes.
