Super Smash Bros. Brawl (Wii)
Okami (Wii)
Spore (PC)
Starcraft 2 (PC)
Tales of Symphonia: Dawn of the New World (Wii)
Then, because lately I get most of my games on the first day : Lost Winds, Dr. Mario, Bomberman Wiiware, Pikmin 3 (if it comes in 2008), Obscure 2 (Wii). And probably many others that are still "maybes" so far (like Left 4 Dead (PC), Alone in the Dark (PC or Wii), Lego Indiana Jones (Wii), Ninja Gaiden Dragon Sword (DS),... )
