Wingreen is staying and Morrison's voice will be altered for the PT. That's one of the 'written in stone' audio choices for the Revisited series, and there are no plans for a purist version of ESB:R.

What the buckethead says is the truth. I'm so excited to only have ONE version of ESBR, instead of the 4 different ANHRs (not including the NTSC/PAL differences).

ANHR has:

XVID AVI which is a different version from the
DVD5 (PAL/NTSC) which is a different version from the
DVD9 (PAL/NTSC) which is a different version from the
PURIST DVD5 NTSC.

ESBR will have:

DVD9 (PAL/NTSC) which will be the same as the
AVCHD (playable in most Blu-ray players)

AND THAT'S IT!

Besides, putting Wingreen's voice back in would be a simple fix to do for the individuals who want to have it.
