Are we sure that Disney is trying to drop ABC, when the network is on a tremendous upswing as far as ratings are concerned? Heck, their Sunday night offerings (Desperate Housewives, etc.) are arguably the most watched television today - and don't forget other big ABC hits like Lost, Boston Legal, Dancing with the Stars, Extreme Makeover: Home Edition, Grey's Anatomy...not to mention the daytime soaps that will ALWAYS bring in big numbers, since they're the most iconic daytime dramas going today - and, they've got the contract with the NBA to run on ESPN and ABC, which if they sold the network could cause tremendous problems for the NBA as far as advertising goes. Just seems foolish to me for the Diz to sell ABC when it's on it's way up - it would be like them selling ESPN back in the late 90's early 2000's when it was at it's peak.
As for Pixar being added to the name - I, personally, don't care for it, but I wouldn't mind if they did. Last I checked it's got the MGM name branded to it, and there have been very few (if any) MGM properties filmed on location.
If I had my preference, though, I'd like it to be Walt Disney Studios Florida - but that's probably a pipe dream.
