I'm pretty sure that GH3 will sell the best on the PS2 solely because GH: 80's Edition will only be released on the PS2 (for the time being at least) so a lot of people kept their guitars and wouldn't want to buy one for the other systems.
After that, it's going to be a toss up between the 360 and the Wii. If the new controls on the Wii turn out to be actually good, it will come out on top over the 360, it now, the 360 version will outsell the Wii.
I really don't think the PS3 version will do better than the others because 1) it hasn't been on any other system before and 2) it won't offer new controls to lure people into buying a new guitar.
