Here are the rules:
1. The game must be released in 2010.
2. Only count what you think the game will sell by the end of 2010, not what you think it might sell after.
So here are my predictions:
Wii: Zelda Wii (I can't find many interesting games that will sell a bunch on the Wii this year, but if anything is going to crack a few million this year, it will most likely be the next Zelda Wii title that's rumored to release this year).
Xbox 360: Halo: Reach (This is a no brainer. I don't even think the new Call Of Duty game set in Vietnam will outsell this thing. It's rumored to be the last Halo game from Bungie, so it'll be big. But it's also not a true sequel, either, so that could hinder it from overtaking Halo 3.
PS3: Gran Turismo 5 (If it ever comes out, that is. Anyways, GT5 is looking to make a splash this summer or fall, and if it does, Kratos will lose the honor of starring in one of the potential top selling PS3 games of 2010- God Of War 3)
I would do a prediction for PSP and DS, but I don't mess too much with portable gaming anymore to make a decent prediction. I would've included PC as well, but sales are too hard to track on there.
So tell me your predictions in these categories and tell me what you think. Feel free to add PSP, DS, and PC to your list as well if you have a good prediction. Thank you for your responses.
