At least a couple of Tinkerbell features are in work. And there are two new installments of Planes on various Cintiqs.
There's also a bunch of new shorts being done, so there are short subjects in production at every division of Disney.(Features just now has Get a Horse, Disney TVA is producing a series of edgy-yet-retro Mickey shorts, and DisneyToon Studios has got a batch in work.)
There's lots of projects in the DisneyToon pipeline, and it isn't all slated for little silver disks. Per Mr. Lasseter:
Disneytoon Studios was started a number of years ago to feed into the direct-to-video market, but as the home video sales have continued to decrease rapidly we are looking at the evolution of the studio going more theatrical. ...
I gather this means that DTS will be the low-cost Disney cousin that releases films to support clothes, games and small plastic toys.
