These are pretty much my thoughts on the subject as well.
Buying the existing blu-ray is a much bigger and better example of making the wrong vote with your wallet, which is exactly why I never plan on doing so.
At this point, I would honestly be more surprised if a restored OOT wasn't on the shelves by this time next year.
While I really don't see any boycott happening (or mattering at least), I do think such a release will drum up good faith and interest in the franchise from old fans who have lost interest after 1997-2004. But again, probably won't make a big difference in the scheme of things. It's going to be a financially successful film.
