Listening to PJ, FW and PB on the commentary tracks of the EE's, PJ mentioned a couple of items which may be taken literally or with a grain of salt:

1. PJ mentioned that he may possibly re-release a 25th anniversary version
2. For the possible 25th anniversary version, PJ would like to tighten up the CGI of Gollum in FOTR and the wargs in TTT.
3. There are additional scenes that did not make the cut for the EE's. Whether PJ chooses to integrate these into the EE's or to just have an area for Deleted Scenes is anyone's guess.

And I own both the widescreen theatrical and EE versions

My preference is the EE's. The commentary provided by PJ and the commentary with the actors are good, that is if you can sit long enough through these.
