Not tomorrow, guys. It's possible today. First we have to be able to read UDF. Then we need the key for decryption (that's why I mentionrd MakeMKV). Then, we'd have to do some conversion 1080p to 7290p). Mone of this has to happen in real time.
Finally, once we have the 720p files, we have enough CPU/GPU power to play it back.
How many LCD TVs are limited to 720p?
We could do this and we could do it now.

The G5 is only necessary if you insist on playback direct from the disk.
