I haven't heard anything about blu-ray technology whatever if it will uses H.264 (A.K.A. MPEG 4 Part 10) video codec as standard?
Image if blu-ray uses full HD H.264 over MPEG 2, it would be doubled time!
It would be huge advantages if they uses H.264 over MPEG 2.
Check it out at

What do you lots reckon?
P.S. Vote for MPEG 4-10, MPEG 2 or other video code...
