I want to add to what mdrew said that there's a lot of FUD going on about the whole DTS HD:MA on ps3. The hardware is capable of decoding it, what it can't do is bitstream it to a receiver due to the fact that the HDMI chip used in the ps3 isn't capable of it. But there's nothing that would stop it in theory from decoding it and outputting PCM.

The question is can/will it be done through a future firmware update? We don't know and if DTS HD:MA is important to you then I wouldn't buy one and then hope it will be included. Since my receiver is old I didn't care about it and so the ps3 is more than enough for what I need. By the time I'll upgrade my receiver either the ps3 will be able to decode it or there will be better and cheaper players to buy so I don't worry about it.
