PS3: Resistance, Virtua Fighter 5, Motorstorm, Tekken 5, Calling All Cars, Ninja Gaiden Sigma, PS2 games galore
Wii: Zelda, Rayman Raving Rabbids, Super Paper Mario, Wario Ware, Virtual Console games galore
Not a whole lot, but more than enough to keep a person busy for awhile.
Besides, both are a hair over 6-7 months old. The 360 better have a better library...it was out for a year before them both.
As stated before, we have a console with great games but is a hit or miss when it comes to playing them (more and more, I find people "put up" with whether a game will freeze up on them, not play, or is just plain quirky), and two consoles that are too young to have the library the 360 does. This holiday season will be an interesting one indeed.
