I won't be pre-ordering White 2. In all of the years I've been a gamer, I haven't once pre-ordered a game. That being said, I will admit I plan on pre-ordering Kid Icarus: Uprising simply because of the fact that in doing so, I can get a remastered version of the original Kid Icarus, which just so happens to be my favourite NES game.
I'll definitely be buying White 2, though. It's not because I buy every game in the series, either; it's simply because Nintendo shocked gamers worldwide — myself included — by not creating a mere third-entry game. That, and it's been quite a while since I've played a Pokémon RPG.
