I’ve been thinking for awhile that an OOT release in 2017 is inevitable, and I still think that’s the case, but I don’t think the way they’d announce it is through Peter Mayhew’s twitter feed.

Don’t see why marketing would clash, especially if the set is released in May 2017. A home video release is not going to overshadow a theatrical release, even if it’s the Holy Grail of home video releases. If they do a theatrical rerelease it would clash, sure, but I don’t think they’ll do that (besides perhaps a marathon before VIII).
