ATI is at least working on it, should be coming out sooner, ATI execs are going to get on the software team's asses, families will have a lot less time with daddy (or mommy), but our drivers are going to come out a hell of a lot sooner, competition ftw!
quote from dave baumann on our forums:
Bear in mind that all of this takes time, even though its largely a software path from here, it does still take time to implement software. In real terms Eyefinity is actually less than 6 months old from a hardware perspective and so the software guys have had to rearchitect the display driver software to cope with the new display capabilities and then add on the features for Display Groups and the bezel management work that is in the pipeline at the moment; a lot of this could only begin when the chip became real and they started going out of the hardware bringup team into software feature team.
