It's just a dummy set. Ricoh is still asking for users' suggestions on what features are wanted/needed in this new camera, I guess we'd be lucky if we really see this camera come out before Christmas. Which might be a good thing, so they can sell some more KS2 before the FF comes out

If a company at this stage is still on the fence and having to ask for users' suggestions, then I fear this company really doesn't know what direction it wants to go. Playing catch up is really difficult in the commercial world when you're not even no.2.
