The Orlando Sentinel reports that three weeks after General Motors Corp. filed for bankruptcy -- and nearly three months after an internal deadline to resolve the issue -- the carmaker's status as sponsor of one of Walt Disney World's marquee attractions remains uncertain. Executives for GM and Disney have continued to negotiate a possible contract extension to keep the beleaguered Detroit auto giant as sponsor of Epcot's Test Track. But so far nothing has been announced. Neither side is talking, at least publicly. "We have nothing new to share," Disney spokeswoman Andrea Finger said recently. A spokeswoman for GM did not return messages seeking comment.
