I'd expect a proper Star Wars VII trailer to be attached to Age of Ultron, and if we don't get an announcement about an OOT box set around the same time or at least by the end of summer, I'll be a little concerned. Novemberish would be a perfect time for a release to simultaneously cash in on Christmas shopping and Episode VIl hype so if we don't see a release around then I'd suspect that it's not going to happen at all.
I love Harmy's editions. I recently got a blu-ray burner and they sit proudly on my shelf next to my other favorite blu-rays, but I'd replace them in a heartbeat with an official version (assuming the quality was comparable)
