Speaking at CES last week, Microsoft's Robbie Bach has revealed that over "70 or 80 percent of the publishers in the world" are currently working with Project Natal.
Speaking in an interview with CBC, he said:
"We have something like 70% or 80% of the publishers in the world already doing Natal-based games. Our first party studios are [also] very focused on this. We want to have a few titles from Microsoft that show the way and then we want the breadth and power of the ecosystem from our partners to bring lots of new ideas, new innovations, new concepts to the marketplace."
Bach further added: "Part of the reason we showed Natal at [E3 2009] — which is actually a little bit risky to be honest because it’s a new technology, very cutting edge and relatively early in its development — is that we wanted third-party publishers to know that it was real and we wanted them to have developer kits and to get them working on it.
Microsoft revealed last week at the event that Natal will be out this holiday season.
