The latest firmware has upgraded the ps3 to profile 1.1 already. Also it can play all formats but DTS HD:Ma and while its hardware very likely can't stream it, it might be able to decode it and send a pcm stream to the receiver, which would be good enough for me (when I upgrade the receiver).
Also the ps3 does support 1080p24Hz since firmware 1.8!

All in all I'm very pleased with the perfomance of it as a bluray player.
