@Yancy Coming to you as a guy who can find something awesome to like about practically any era...
1. Of course the younger demographic loves Clone Wars. They've been raised on the prequels no different than we were raised on the classic trilogy. It's their Star Wars. Since the Disney buyout though you can pretty much look across all the project lines and see a massive shift back towards the classic trilogy, wether this be in the form of the upcoming animation, Battlefront 3, the new card, minis, and board games, even episode 7... all of it. Old Republic era has been rockin' strong since the early 90's and it seems apparent that the creators behind the scenes are are ready to shift to a different era rather than continue to beat one particular one to death. This isn't a right/wrong kind of thing, it just seems like a deliberate set of steps, and honestly it's probably smart business. I'm not much of a homebrew guy unless I'm creating something with Fate or some other open system, but coming up with a custom era setting may be the way out for folks that have to play in other eras, and really all the tools are there so why not do it?
2. Take a moment to consider this. You're Force sensitive. You've been born in the back end of space and are pretty much removed from the "classic trilogy" events so you're not even aware of the fact of what that is or what that even means. Over the course of your adventures you not only discover more about yourself and the strange things you can do, but you also start discovering this galactic history that takes you on a quest to discover what it all means. In the past the Jedi were either farmed from the youth, or we saw the frayed ends and beginnings of lines. There's a really cool opportunity here for a new kind of "Jedi" journey for the right player with a creative mind, and to me at least that seems pretty exciting.
I think "canon" as we know it, especially if you're looking at the EU book and graphic novel lines, is probably going to get bumped around a bit over the next few years. The few of us diehards who have read Zahn will no doubt twitch and a few of us will probably fly into an online fit of Butthurtery. But in the end this epic story and franchise will not only be fine but outlive all of us. Why not see it change and grow? Just imagine the New Kids in a few short years that will have 7-9 as "their" Star Wars. What kind of fan community do we want to have waiting for them? Wise Jedi Masters or a bunch of whiny moisture farmers?
Let's see what FFG comes up with and not worry about Clone Wars product line #5467. I think it will be awesome, myself. And I think the kids will get into it as soon as JJ is done doing his thing.
