Well yeah, those 360 games you mentioned are great because they're basically second generation games. If you wait, you'll get games like SSBB, Super Mario Galaxy, Metroid Prime: Corruption, Prince of Persia, Mario Kart, and probably a better Red Steel 2. Sorry, but most videogame systems are dull for the first few months they're out because most launch titles are lame. This time next year, or even by this summer, you'll probably regret selling your Wii.
That's my opinion.
