For what it's worth both companies ( AMD & nVIDIA ) have been very secretive the last few months, and do their best to make sure nothing really useful gets leaked ( months before the G200 launch I had archit. info that I partly released and other people had that and other info as well, this time nada from both companies ).
Does this means that they both have something good in their hands ? Possibly.
But it could be the opposite as well.
