Got more info on AMD chipset roadmap, here it is

*sorry for the crappy "roadmap"
I can also tell you that the development of RD790 is going smooth, ATI already has working samples for a couple of months, the first revisions could run Windows with legacy specifications as HT 1.0 & PCI-E 1.0
TSMC 65nm process is working perfect
