Your ignorance is starting to get on my nerves.
1) Yes, we don't know for sure that it will be the same transfer but from all the information we have it just seems more than likely.
2) What transfer it is has absolutely nothing to do with the capabilities of DVD or Blu-Ray. The transfers for DVD were done in 1080p and then downscaled to 480p for the DVD, so they can be used for Blu-Ray. But they were done poorly, so they look like shit in 1080p VC-1 just like they did in 480p Mpeg2.
