Not sure the cheap and easy applies to feature films. Pixar and Dreamworks employ small armies, and the budgets often rival live action projects. And it still takes a few years to actually make one.

There are CGI animated movies that have been done cheap, (and sometimes nasty looking) but not by the big boys.
Has any budget for VII been mentioned or speculated at yet?
