Those look like pretty realistic specs to me. It would mean, that we could see a very decent jump in graphics quality over the PS3, but the console could launch for $300-$350 without much subsidizing on Sony's part.
I just hope that they still go with a Southern Islands architecture GPU(like other rumors mentioned), which the 7670/6670 isn't. Maybe it's a typo and they actually use the 7770 as that one comes with 1ghz clock, but ofcourse console GPUs don't necessarily need to have the same clock as the graphics card the respective chips are used on.
