Once the new movie is on the screen it's canon. With the new canon proceeding forward, TNG, DS9, and VOY will cease to exist as we know it. There won't be a revival of something that no longer counts. That's why it's kinda sad for me, I will always consider myself a TOS fan first, but i loved TNG and DS9 and the progression it took. Now, IMO, none of it will count. At least in the way we knew and or know it. With a new look and timeline the progression of the Star Trek universe could go in a direction that could ignore TNG altogether and it doesn't matter at all what was done before.
I guess in the end it's a whole growing up thing. Star Trek has been on my entire life. It's always been what it's been, take it or leave it. Well I chose to take it and its been a part of my life everyday up till now at age 32. Everything I have always loved could no longer matter.
Now we have a re-make coming out. This re-make has the opportunity to be great, but it also has the opportunity to take a nose dive. Which ever happens, the same result occurs. Everything from here on out will be different than what i have known my whole life as great. There could be a new TNG down the line but i don't think the franchise would be allowed to survive to that point, either it be by fans, the production companies, or general movie/tv audiences. By the way JJ has said the new movie will be for fans of movies, meaning general audiences.
I would love it if there were no re-make coming out and there was an actual revival of the TNG era, late eighties and early nineties. This new movie however changes everything though. In one year's time, the last 40 years will become obsolete.
