I cant imagine how the show can work without him, one of the amazing things about the super-long run has been the core voice talent doing what they do for so long.
And for everyone wondering why the show isn't just dying? It makes money. The ratings are still good, and the merchandizing money is still good. No executive in their right mind would pay voice actors $14m contracts and order 2 seasons in advance for a show that apparently nobody is watching, at least not if they like their job. It isn't as good as it once was, but it could be far worse and there's still plenty of people who find what's on offer to be entertaining.
It's possible that there's talent out there that can emulate Shearer's work, but the show would definitely have a different feel to it. He might be making a power play for more money, but then the other actors would want that same amount and we'd have a clusterfuck again.
