Do you think they will make a Grand Theft Auto game for the Wii?

the might, they might

depends on sales (like you said) and rockstar itself

Yup. I have never liked GTA, but they will if Manhunt does good.

I'd really like to see a non realistic Nintendo themed GTA...kind of a smash up of Mario platforming, Mario Kart, Zelda weapons, Metroid upgrades, brain training for increasing stats. But it will never happen.

Quite possibly. I don't think Rockstar could ignore nintendo if manhunt 2 does well.

Hopefully, it's been expected a lot that GTA would come to Wii. I am not a big fan myself either but it would be good with sales and provide more for gamers.

They're probably going to be paying more attention how well Bully does. The whole AO controversy is already going to ensure high sales on every platform similar to hot coffee (though not as major I think).

Bully is pretty much just a GTA mod and will tell much better how an old Rockstar game will do on the Wii.

 That's just gay.

I don't think that a new GTA will come to Wii. More likely a new IP or something like Bully 2 (better IMO).

 Can I have your dog ?
