There are six other Bond movies coming to Blu-ray too so consider it an investment in the future.I want the Blu-ray, so I need a Blu-ray player, and if I have Blu-ray I want to get the most out of it, so I'll need to buy a good HD TV. Depending on the deals I can find, I'm probably going to be spending at least $600 just because of Casino Royale.
That'll help, the actual price ended up being twice my "at least" estimate.
