Well,
As it's not confirmed, it must be a rumor lolz.
That might explain the deal on GTX470s on NCIX maybe?
End of the road for GTX470? | KitGuru
Who knows...
if it's true, in my opinion, it proves that NVIDIA wasn't really ready for the FERMI launch when they did, but they just opened the gates, let a few FERMIs out, to keep ATI from getting all the DX11 market share and try to "stop the bleeding" as a temporary measure.
On top of that, if it's true, it proves that GTX480 is not really appealing and that everybody should wait for GTX485 (or whatever naming scheme is gonna come out). Just like the GTX280 versus the GTX285...
