For what? The audio? I very much doubt it'll be a case of sync and go - there'll be frame differences at all the reel changes at the very least. Whoever syncs this will have to do a fairly precise job of it, and the best reference will be the DTS-HD from the Blu to ensure picture sync (MGM logo and all).
After the two have been matched up, the logo can be eliminated at the mux stage for those who so desire.
