With The Clone Wars improving a lot in its current second season and getting progressively darker, Lucasfilm is obviously worried that Star Wars is getting good again and so are planning a new animated series for pre-schoolers. Yes, kindergarteners, nursery schoolers, or those annoying brats that Anakin brutally murdered in Episode III. Presumably that last scene won't make it to this new series.
Anyway, the working title is 'Squishies' for god knows what reason, and is reportedly based on the popular/crap line of squat toys called 'Galactic Heroes'. What part of the Star Wars timeline it will cover is anyone's guess.
Star Wars Babies next, anyone?

Seriously though, I'm looking forward to the live action imperial-focused show they're working on.
