What he's basically saying is for the next 6 months easily you won't have any real Wii games you'll want to buy. Where the 360 is the complete opposite.
E3 was a total joke. Nintendo didn't address their VC problem, hard drive space, Mario Kart Wii lag hackers, SSBB lag, and you get the theme here.

This of coarse applies to core gamers who play their console 4-7 days a week.
