I don't understand why they'd release it then if it's true. I doesn't make sense any more after the 7970M. I hate how they keep releasing these renamed/rebadged underpowered cards. Unfortunately I will still get Nvidia cards for my 3d work. Probably won't upgrade to this anymore though.. My 675M (when it gets here) will just have to do until I can get myself in a situation where I can actually own a desktop.eh.
Shame. I do hope they surprise us, but with the track record, probably not. They'll probably come out with a 685m out of nowhere like they did with the 485m after I ordered the disappointment that was the 480m.
It's quite possible that the leaked benchmarks are from the canned 680M R1 and that they will announce a revised version of the chip. I twill definitely be a GK104, possibly with more coreds thn the announced 768... or if the specs are indeed correct it could be planned as a 75W GPU with a 100W 685M / 780M to follow.
