I have to say that I've yet to find a blu-ray disc that my ps3 coudln't play or would skip on. But I agree that if DTS:MA is important to you then there's no guarantee that it will ever be available on it (while it's certain that there'll be a 2.0 profile update at some point). In my case I don't care since I don't have a newer receiver that can decode multichannel PCM over hdmi as well as the decode the new formats.
All in all though the ps3 is the only blu-ray "player" on sale right now that has the possibility to be upated to match any new player. By the time it's obsolete there'll be cheaper and better players for me to consider.
