I think it goes without saying that we are all pretty much huge Sci-Fi geeks. and its been documented ad nauseum what JJ Abrams did with Star Trek - the good and the bad. To be completely fair there was a lot to like about the new Star Trek, even if it has some REALLY annoying departures for us hard-core fans.
But the Star Wars gig is different form the Star Trek Gig. Trek was just about dead from the movie perspective the abomination that was Nemisis killed it (I can't bring myself to watch it a second time). The TV shows had petered out, although I do admit the 4th season of enterprise was pretty awesome but too many people had given up on it by then... the Star trek task was to reinvent and reinvigorate the franchise. The Star Wars Gig is to continue the franchise and grow it. With that in mind I really think that it will be more of what we are used to seeing from a film perspective. CG or real model.
To the topic of this thread - I hope real models are used (more) as well... they just look better. But I think that the real failing of the prequels FX was that everything was filmed in that high def digital camera... and everything looked a bit "off" even if it was live action... It may have been much easier to digitally edit the film that way but the look of the films suffered IMHO. Perhaps the cameras are better now and they can achieve that film grain look now... But attention to how it looks is a biggie. Please limit the lense flares
Breaking out soapbox here...
Also the advent of CGI being a primary FX method has led to sloppy film making IMO... Too often the director can get any wild ass thing that pops into his head on film... But the creative process of figuring out "how do I convey this plot point within the limitations I have" I think often lead to better story telling as the director had to really think and understand the story to get around the limitations of his technology. That extra thinking and planning paid off in STORY elements. For example one of the best scenes in Star Wars in terms of character development was the
- HAN SHOT FIRST- scene with Greedo... In one brief scene we learned that Han Solo is a Bad-ass, with a deeper backstory then the dude who takes the lightsword guys to the big planet killing moon. That entire scene was a fabrication since Lucas could not get a satisfactory Jabba for the encounter at docking bay 94... And the resulting scene was FAR superior, even after the tech was there and the digital jabba added in.
Soapbox put away...
Mr - Abrams - please make us a great movie

Please pay attention to the story. Please select the best technology to get the best look for special effects and don't just grab CG because its easier... The most classic shot in all of Star Wars to this day is the opening of ANH... Done with Models on a shoe string budget by college students
