I'm not quite positive on this one. I can see the next Single Player Bethesda title to be 1080p and 60fps; but we're talking about an MMO; they always seem to downgrade when it comes to FPS whether it be on Console or Computer.
Take PSU(Phantasy Star Universe). On the PC at the time of release, it could sustain 35-45 FPS with other players around you; when you popped onto the Console(360/PS2) it dropped down to 20fps.
I'm sure it'll stay 1080p but when it comes to the FPS it's up in the air..
