Early adopter's dilemma

I have been back-and-forth about Blu-Ray. Is it worth committing to a new format, when probably in five or ten years we'll just be downloading in hi-def? If I do get a Blu-Ray player, should I get a PS3, which is allegedly Profile 2.0 compliant, or do I wait for fall, when the newer, cheaper Profile 2.0 players are supposed to come on the market?

Now Amazon is trying to force my hand with a Buy Two Get One Free sale on Blu-Ray discs. What do you think, readers? Should I take the plunge, even if I won't be buying a player for a couple of months?
