Sony Computer Entertainment Europe chief Andrew House reckons Microsoft will struggle to develop a broad range of games for Kinect.
While Move can work with any genre, he feels Microsoft's camera-only motion control solution has "limitations", as Sony found out with EyeToy.
"We learnt from that experience that there are limitations around a camera-only solution. It does work well and lend itself to certain genres, but you do tend to hit a bit of a wall when trying to support it with the broadest range of content available," House told MCV.
"That's not the sort of problem we have with Move. Consumers have understood Move is something that could impact a wide range of games. This is opposed to what I think may dog the competition to a degree, which is basing it solidly around just a family experience - and one that is harder to adapt into traditional game genres."
He added: "We've got a whole range of experiences that serve the broadest audience and that is a far better long-term bet... It really will be content that defines it."
While Kinect titles to date have certainly catered to the 'expanded audience', Microsoft said over the weekend that Forza 4 will support Kinect.
Move support has already featured in games like Heavy Rain and Resident Evil 5, and been confirmed for Killzone 3.
