As the Times says:
[Puss In Boots] marks the first time that the Glendale studio has relied on a crew of Indian animators to help produce a full-length feature film. Until now, DreamWorks Animation had used the studio it operates in Bangalore to produce mainly TV specials and DVD bonus material.
... Joe Aguilar, head of the Indian operation for DreamWorks and producer on "Puss in Boots," [said] "There has been fear in our studio. But, if anything, we've just built more space in Glendale to increase our capacity there, and we're moving into a bigger office in Redwood City. We're not reducing jobs in the U.S."...
Couple of things about this: There has been downsizing at the Glendale facility. But this has more to do with shifting production schedules and production delays, not with outsourcing.
To DreamWorks Animation's credit, when production gaps bubbled up in Glendale, work on a Puss featurette was shifted from India to California so that Dreamworks employees stateside had continuity of employment.
So. Will entire DWA features be done on the sub-continent? It's certainly possible, but I don't foresee work on high-end features disappearing from Southern California. Salaries are only one part of the production equation.
