I heard about this benchmarking as well - I get Google Email alerts on the Transformer 2. Just hope it's the real deal. Strange the results were taken off the original site, though.
The Transformer 2 DEFINITLY is coming, although we don't know exactly when. To the best of my knowledge, ASUS' CEO stated Q4 2011; so it IS coming this year. There's a link to another article on it here; although it didn't really give any hard info.
Would be great if it arrived in time for the holidays, not that I'll be buying one since I just recently became the proud owner of the original Asus Eee Pad Transformer and won't be needing a new tablet for a while, but for people still deciding on what tablet to get the Transformer 2 sounds like it will be a great device!
