If they completely buy them out, they will probably be able to say just "Disney", though the opening credits and such will of course still say "Disney/Pixar." However, I don't think Disney will be looking to distance themselves from Pixar. They will probably want to encourage the notion that Pixar is just a branch of Disney CGI films, which is what a lot of people seem to think anyways. Still, they may lay off the whole "A Walt Disney Pictures Presentation of a Pixar Film" business, just for sanity's sake.

Update:
This is an exciting article, not only because it announced that Disney will announce $7 billion take-over big for Pixar in just a few hours, and that it is expected to go through, but also because of the optimistic view it takes of the buy-out:

Another interesting article that analyzes that $7 billion price tag. The author says it's a fair price and breaks it down in a way that makes sense. He, too, views it as a positive move for both (especially Disney) and I also like that he puts a high price on Disney's perception of quality by the public, something that Disney themselves rarely do.

The Disney board has approved the offer and authorized Iger to make the offer to Pixar. The Pixar board is expected to confer by phone and possibly reach a decision today (sooner than I thought!). If that happens, Disney could make the announcement of the purchase of Pixar after the market closes today: <B><a href=

Several of these articles have mentioned that Disney may be hoping to move into the digital movie market via Apple with Jobs on the board.
