so If I go Blu this summer should I go with Sony's player or a different one?
Sony, Panasonic and Samsung are all shaping up to have a good one. I'd wait until you get close to buying one and then evaluate them all, to soon to guess if you are going to wait a few mo's.
As far as waiting for BD to be the standard, if we all did that none of us would have purchased an HDTV early, I have personally had one for 4 years and I know some on here much longer.
As stated above, evaluate it yourself, just beware there are guys on this forum and others that are bitter and will use negativity to sway you. Just decide for yourself.
I spent $499 on a player and have not looked back while buying a disc a week(some catalog like I robot, some new releases like Golden Compass) and I use Netflix for the rest. If you rent from netflix, 90% of your major studio rentals are BD right now and thats going to be 100% soon with Univ and Paramount coming.
I think BD may survive, some think not, if you are worried about that then dont buy in and let us early adopters enjoy it. If you waited to see what was going to happen with every format, or always waited for next years model because it may be better/cheaper, then you'd never buy anything
