I thought Disney wasnt showing much at Comic Con, and instead was waiting for D23(even tho nothing has been announced for the expo with a month to go)
I understand why they didnt do much merch for Up, given Wall E stuff didnt sell well. Then again, robots arent very cuddly.
People are free to believe what they want...but there is simply no established canon that unifies Muppet tv shows, specials and films. It's not like Star Wars. The only real "canon" is when you see Gonzo, Pepe, Kermit, etc on a talk show. Though, is there "canon" with Disney toons or WB Looney Tunes? There is with Pooh, sure. But Disney toons and Looney Tunes seem to exist only in separate shorts and films.
