I thought Nestle's logos were down earlier in the year? All the reports talked about it for awhile? I honestly haven't been there since July, 2007 and this all happened after. Or so I read. Great if they didn't.
GM isn't confirmed, but likely. Especially if they've noted their sponsorship in the past and now it's removed from their list.
I also agree, this isn't Disney specific. But, when it comes to Epcot it seems like the only love a pavilion gets is if a sponsor puts up the funds. Nemo is an exception, but I personally think it was a video screen downgrade.
Here's hoping Disney uses their sponsorless freedom to do something better or finds a new one to partner with them. The transportation pavilion wouldn't have to be sponsored by or themed around cars... I'm just saying...
