Definitely Borderlands 2 and Ni No Kuni.
I'm still a little on the fence about Bioshock: Infinite and Torchlight 2, but I'm leaning towards a day 1 purchases.
I enjoy day 1 purchases. There's something about being able to play the game at midnight on the day it came out that really appeals to me. 95% of the time I end up happy with my purchase too, so the odds are good enough for me. In recent memory I bought Fallout: New Vegas, Dark Souls, Tales of Graces f, and Skyrim, and all those have been worth the money.
