There are many games coming out in 2007 that are great for ps3 and xbox 360
PS3:
Singstar(downloadable content of over 300 songs will be awesome and will be the ultimate party game)
Warhawk
Lair
Hot shot golf 5
Heavenly Sword
Ratchet and Clank future:tools of destruction
mgs4
tekken 6
killzone ps3
uncharted drake's fortune
eight days
2 unannounced games by zipper, and sucker punch (so they will most likely be aweseome games)
Xbox 360:
halo 3
mass effect
forza 2
shadowrun
tenchu z
blue dragon
too human(if that report doesn't come true and is delayed till 2008)
In my opinion, I think that the gaems on ps3 are going to be better then the games on xbox 360 this year. If none of these games get delayed. But that is me.
Also Home is coming out on the ps3 this year too :).
