Just to bring this up, as it could like some implications of where they are on vocal work, Patton Oswald made his debut as Max for replacing Louis CK in Pets, as a small piece to CineCele, the new night time show at USF.
What interests me, is that I think that it might actually imply that they are not only done with him recording for Pets 2, but they may of had him also do recording for not just CineCele, but perhaps Pets USH, just to get things taken cared of.
It wouldn't be the first time Patton has lended his hand for theme park VO, as he did act for WDI on Ratatouille for Paris (and Epcot, but that ain't open yet though).
Just food for thought.
