It's funny some guys are surprised by that situation.
In the Level Up discussion of May 07 between N'Gai Croal and Geoff Keighley (hope their famous enoug !), you could read that from GK :
"Already third party executives are telling me that if PS3 sales stay below 100k for 3 consecutive months, PS3 SKUs may start disappearing from release lists and in turn create a wealth of de-facto exclusives for the Xbox 360. Sony could stem the tide by supporting third parties financially with co-marketing for exclusivity (or even buying an exclusive window on a game), but I continue to hear tales of Sony expressing a lack of interest in securing third party exclusives."

The way Sony act has probably change, but the situation regarding sales remains difficult.
