Someone will. It really makes no difference who. The day no one is interested in doing it under whatever name is when it will matter.

I think FOX should stick with Dreamworks. Only other studio I can think of is Universal and they have enough success with Illumination's Despicable Me films. Most studios seem to be content with animation having a project by project basis, not dedicated in house stuff.
Then again this article states how Sony may want to considering their lack of movies and they see difficulty getting good results on their movies, and I for one do think that Sony would be a good partner for Dreamworks compared to the other distributers.
I think DWA is going to struggle financially for the next few years. Their upcoming slate doesn't look like it has the kind of energy they did in their early days. Most likely they'll be turning out moderately-performing films like Turbo, Home, and The Croods for a while to come. Another distribution partner is probably going to come easy to them, considering their standing within the industry, but most studios already have their own animation division. A complete takeover would probably be a better move for any prospective buyer.
Katzenberg's revenge mission to Disney is complete, for the most part. He proved that other studios can compete against Disney. However, the studio seems to be heavily reliant on its cash cow franchises and might be losing ground to Illumination in the second-banana-to-Disney spot.
DreamWorks Animation can't sustain itself for much longer. It's kinda hard to believe that DreamWorks went from a motion picture distributor back in the 1990s and early 2000s - backed by Jeffrey Katzenberg, David Geffen, and the legendary Steven Spielberg - to an animation studio whose films are being distributed by another company.
If such a channel would exist, it would be something similar to what Hoolee was in Africa, Dreamworks shows were the main output on that channel (apart from Turner's own shows). It would be Dreamworks + Third Party shows.
In retrospect, Dreamworks shouldn't of split, or Dreamworks Animation shouldn't of gone alone.
