I have seen the question of why not clone wars pop up a few times in the forums here and, rather than start a whole new topic on someone else's thread, I decided to post my thoughts here.
I doubt we will see clone wars support for a long time. Right now, the focus seems to be original trilogy to lead us into next December, when episode VII is due for release. Very likely, this will be followed by episode VII stuff. Finally, after that has run it's course, then we might see a return to clone wars.
Why would they leave that era untouched? First off, clone wars is not a focus of disneys campaign for advertisement. Their games would stand alone. Second, the prequel trilogy is generally disliked by fans and casual moviegoers alike. It is true that the clone wars series was better liked, but nothing like original trilogy stuff. Finally, there is nothing motivating such a radical change. The original trilogy stuff is selling great and has very positive reviews.
On the other hand, they might be launching all of this stuff to build off each other's popularity and, once they have run their course, they will launch another, mutually supported, series of game systems. Maybe that's why they timed the RPGs like they did.
But that's just my thoughts on the matter.
