Right now, they're possibly the two most important questions gamers have concerning Project Morpheus:
How many games can we expect to see? How much will it cost?
While Sony can't put exact numbers to either query just yet, Sony Worldwide Studios president Shuhei Yoshida offered comments on both topics to GameSpot in a GDC interview. Firstly, Yoshida says "many studios of ours are working on actual games" and while they can't talk about those titles yet, they might show some gameplay at E3. He's "so excited" about these games but he can't wait to see what devs do in the future:
"I'm expecting a developer that we don't even know exists today will come up with something amazing. What excites me most, from our experience launching many platforms, is that it's always someone who we do not expect that comes up with totally new ideas and blows anybody's mind."
As for price, Yoshida said they're simply looking for a price tag that's "as low as possibly can be done." They want to give consumers an entry point so it's at least accessible; if they can do that, the device has a better chance of success.
Personally, I have no interest in it but I imagine it could be a game-changer (pun intended) for a great many.
