Given how nicely the PS3 will upscale a normal DVD, and given that half the films you named aren't available in high-def yet, Blu-Ray is really not all that wise of an investment in my book. Save yourself $15-20 per film, buy the DVDs instead, and put the money you save towards Fallout 3, Oblivion, Bioshock, Dead Space, Mirror's Edge, inFAMOUS, Prototype, Sonic's Ultimate Genesis Collection, Resistance: Fall of Man, Resistance II, or any other PS3 title that you've been dying to play.
