Firstly, rumours, secondly, hope you enjoy the 3d framerate when non 3d will only be capable of the 60fps mark(if said rumour is true, we'll see).
The point being you could do 60fps on the current consoles... the question is what settings does a game use to get 60fps.
What will you be able to get on a PC at 60fps minimums, in game xyz, at 1080p, every single thing maxed out, every option, high res textures, no slow down, what about consoles, textures made smaller, AA way way down, frequent slow down, etc, etc.
60fps, 1080p mean NOTHING so making a dicussion based off them means nothing. Saying BF3 pc level details maxed out completely, 4xaa and 60fps minimum does mean something, its tangible, its a known quantity. Saying BF3 with unknown detail levels, only that it hits 60fps, means something completely different, it could have every graphical effect turned off to reach 60fps and look half as good.
Anyway, lets assume for a second it could run BF3 pc level maxed out graphics at 60fps..... well, I need a PC anyway, e-mail, net, coding, work, learning, tv/film, encoding, and dozens of other things, so I have a pc, its cheaper to buy a new graphics card than buy a console....
So the question is as always, if I have a PC why would I buy a console, if I had a console, I'd still need a PC. Ultimately I prefer to game on a pc, at a desk, in a comfy chair. So many situations I play a game with something open on the second screen, which is just completely impracticle on the console.
