Are you the "Nobody"
who forgot to read the many un-official previews?
How come when you did see the "official reviews"
none said "HD4870, it's crap compared to GTX280"
If your own experience was true it would save NVIDIA lots off money.
Anyway the point was that the NVIDIA did know long time before plus there was only few days difference between the releases.
