Real? Maybe, although at this point it's a bit suspicious that it's not running a dev build of 10.6.3 instead of an internal build of 10.6.2 as reported on the page; also, Geekbench results are frequently spoofed by hackintoshes (unless Apple built an AMD-based MacBook Pro and simply neglected to tell us about it). Fast? Heck yes; the benchmark score of 5260 handily blows by the speed of currently shipping machines.
The eventual appearance of the 6,1 version of the MBP has been a bit of a foregone conclusion since October of last year, when developer builds of OS X 10.6.2 were found to include support files specific to those model IDs. A laptop refresh in Q1 would be a very nice thing, but in this case I wouldn't get the checkbook sharpened quite yet.
Thanks to Ken and Jack for sending this one in.
