Here's a kind of convoluted rumor for you to chew on as we continue to wait for no news about Star Wars: Episode VII. According to an interesting e-mail we've intercepted, and which purports to come from within Disney's marketing department, the studio are planning to re-release A New Hope, The Empire Strikes Back and Return of the Jedi on DVD/Blu-Ray/On Demand in their original form, without all the things George Lucas changed for the "Special Edition" releases back in 2004.
The new trilogy is going to be very closely tied to the original (and not so much the prequels, if you're reading between the lines) and will be marketed as a direct sequel to those, so this particular re-release strategy makes a certain sense.
Going forward and looking at the much bigger picture, there are more dubious rumors to consider, like Disney potentially phasing out the prequel trilogy by lumping them in with the "Legends" non-canon fodder. This has apparently been the subject of gossip near Disney, though it's very possibly just that – gossip amongst the worker bees. Anyway, it would allow for a reboot of sorts, with new prequel movies featuring Yoda, Darth Vader, etc.
But like I said, that rumour is much more dubious. Sure, they probably don't want people to think too closely how disappointing the last three Star Wars films were in the run up to a new release, but to erase them from canon… would be a totally different story.
For now, though, there is room to remain hopeful about a new original trilogy re-release.
