The current poll's results are interesting. Not whether or not Brawl will be the best-selling game of 2008, but which version of Grand Theft Auto IV will do best. Currently, 118 people think GTAIV PS3 will be the best-selling game of 2008, while 89 people think it wil be the 360 version. Some stats to consider:
San Andreas sold over 15 million on the PS2, with a 110 million plus user base, and a little less than 2 million on the Xbox, with a 24 million user base.
However, only 410,000 copies of the PS2 version were sold in Japan, and the database doesn't list any Japanese sales for the Xbox version (it may not even have been released). Obviously it's not a hugely popular franchise there.
The PS3 has a little less than 8 million consoles sold in the Americas and Others, compared to over 16 milion Xbox 360s in the same regions. Though these numbers won't be the same when the games are released, I don't see any reason why the gap would change significantly. The 360 version will have roughly 8 million, or more, users to work with.
Keeping in mind that the game is a legitimate system-seller, which version do you expect to sell more?
