Well, one thing that is cool/different than the prequels is that fans don't really what the new trilogy will even be about. I mean we knew forever (since '83?) that the (if there were to be) Prequels that they'd be about a Young Anakin and Obi Wan and how Skywalker became Darth Vader. Molten lava, the fall of the republic, etc. Those facts were all known so, right away, fans had visions/expectations of what it was to be built on certain, solid, plot points. We had Episodes 1-3 that we had imagined. A bit like reading the book first. You don't really have that with Episode VII. I mean, we don't even know who any of the characters will be. I assume the droids, an old(bearded?), Jedi Master Luke, but I have no idea what the core of the plot will be. I think that can only be good in terms of fan reactions. Unless you have an outcry from avid EU fans that there was no Admiral Thrawn or whatever.
