Have you seen The Clone Wars though? Don't let first appearances fool you, that show has produced some of the most noteworthy Star Wars stories in recent years. In my opinion, it's definitely the best Star Wars has had on the small screen. It's not just kids' stuff either, some episodes handle material the movies shied away from. If Star Trek were to take that route, yes, it will be aimed at kids and their income will come chiefly from kids and not the mainstream audience, but that's not entirely a bad thing. Furthermore by aiming it at kids, it can supplement the movies instead of, as you say, relegating Trek back to a secondary delivery channel. Trek fans, if they are open minded enough, will get amazing stories while kids get a nice action packed series. Mainstream audiences may tune out, but they have the movies to please them. If they do Animated though, I hope Orci and Kurtzman learned a bit from Transformers Prime and fix some of the mistakes made on the show. It was very ambitious and dark, but lost a bit of its direction midway through. Still a good effort though.
