A delayed release of the OOT on DVD seems like a more sensable thing to do. Give it the treatment it deserves (anamorphic widescreen, image enhancement, sort'a like the treatment they gave the Indiana Jones Trilogy). Better still, release it as a seperate boxed set and maybe put in some extra's like the original "The Making Of Star Wars", "SP-FX" and "From Star Wars To Jedi - The Making Of A Saga" documentaries. And than see which version sells best ...

However, I think this is what will happen...
September 2006 will bring us the re-release of the 2004 version of Episodes IV to VI with the OOT as extra material.
In may 2007 the 30th Anniversary Edition box set will be released, which will include altered/enhanced versions of Episodes I to III and the september 2006 release of Episodes IV to VI.

But who knows, GL may surprise us and:
a) include anamorphic widescreen enhanced version of the OOT in the 30the Anniversary Edition box set, or
b) release an anamorphic widescreen enhanced version of the OOT in a seperate box set.

I'm hoping for b), but I'm not going to hold my breath ...
