Personally, I think it may be until the end of the year until Mach4 and all the hardware vendors are fully up to speed. But I could be very wrong I've had a few different versions of this demo for a few months now. Apparently, the development version they're actually running machines with must be very different than the versions I've been able to play with, as they seemed to still be a long way from release. But if I had to guess, I'd say another 3-4 months before it'll even be for sale?
