Maybe ATi are preparing/making headroom for Kepler release. In which a 7980 would surface?
Or is this rumor just baloney?
Supposedly a hard count shows 36 CUs. Could be they wanted to launch first and have a better version ready to beat kepler when it comes out, at least, that would be the smart thing to do...
