None, really, because in my country you can't preorder games (as there is no Gamestop or stores like that).
But I've the money saved up for BioShock Infinite to buy it on release day, I guess that counts somehow.
I think I'm going to add the following games to the list though:
Assassin's Creed III (whatever the best edition is)
Assassin's Creed Liberation Vita Bundle (Will probably keep and not open)
Ni Nu Kuni White Wizard edition (spelling?)
Bioshock Infinite (especially if they offer an ultimate or collectors edition)
