I absolutely doubt it. I'm sure we will get FUNi-like quality, partially upscaled (for stuff that does not exist in HD).
As you can see, big majority of consumers do not have quality criteria. Only format counts. You can slap (properly cropped) VHS rip on the disc and it will be OK - it's named Blu-ray, has native HD resolution, fills the screen and that's all average Joe needs. This is capitalism - forget about good quality if you gladly pay for crap.
Speaking about all the quality issues of the new releases, I think that one of the reasons here is popularity of the show (especially among casual fanbase). They think that it deserves special treatment and they come up with all those ideas of stupidly moronic modernizations. On the other hand, they know that the majority of buyers are casual, so all their ideas can be executed poorly and as cheap as possible. Look at some shows that are less popular than Dragon Ball, for example: Ranma ½, Magic Knight Rayearth, Mobile Suit Gundam, Urusei Yatsura or Slayers OVAs* - all of them are beautiful film-to-HD transfers without idiotic modifications (if not beautiful, at least acceptable)
The second reason is... Toei. They totally don't care for quality HD releases or delivering good masters to their licensees (while DVDs were mostly good, Blu-rays are rather crappy)
By the way, if I would be an Italian fan, I would contact Yamato Video, share my opinion with them and give them audio tracks of the movies ripped from Dragon Box or Laserdisc releases
