Why are games selling so poorly on PS3?

My question is more like: Why do certain PS3 games sell poorly?

I mean, If Call of Duty and Assassin's Creed can tear up the (PS3) charts like they are, why did Racthet fall so hard? And Uncharted? These games were both hyped by Sony and are exclusives, so why are they being passed up for 3rd party games you can get elsewhere?

While no one can say 100% my guess would be:

Heavenly Sword: Too short - people rent instead

Drake's Fortune: Too short - people rent instead/New IP/Looks like Laura Croft Rip-off/Seems to have legs though

Rachet & Clank - Too casual for the hardcore FPS crowd that paid $600 for PS3's.  Has good legs though will do okay long-term

Warhawk - Online only

Lair - ummm.... I've no idea....
