Judge by the number of games you'll purchase from the list not how long the list is. Must-buys IMO are:
On ps3: GOW3, Heavy Rain, Infamous, KZ2, WKC and Uncharted 2
On 360: Alan Wake, Halo Wars, Halo Chronicles, Halo 3:ODST, SO4 and Conviction* (too many Halo games but judging by it's immense fanbase, I can't discount it)
On Wii: Madworld, The Conduit, Disaster:DOC, Wii Sports Resort, Spore, MH3 (don't know about outside JP), FFCC, Pikimin 3 and Little King's Story
When it's all filtered down, the lists don't look very different. The ps3 just has only "dedicated exclusives" much like the xbox last gen. It kinda like how the xbots of last gen used to say that the xbox had the best quality of games. They were right in the sense that the xbox got no "filler" games last gen while the ps2 got lots of "filler".
PS2 is the wii this gen: lots of exclusives but not many that you'll actually play.
Xbox360 is somewhere in between.
Xbox is PS3 this gen: few top quality exclusives but you'll buy most of them.

"WAR is a racket. It always has been.
It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives"---Maj. Gen. Smedley Butler
