I'm not pre-ordering it but so far I'm impressed with what Treyarch has done with the game. Unlike IW, they can scrap everything and come up with a completely new design in less than a year.
I like the futuristic idea and I think it's a bit of an attack on their part with the BF series as the next BF game is supposed to be 2143 (the sequel to 2142). Still, we'll see.
Oh and if they don't put true dedicated servers in, I won't even consider buying it. Treyarch hasn't gone to full matchmaking yet and let's hope that they don't.
