I hope not, but if Jim Davis were going to end the stip on a high note, why not give Jon the woman he's been after pretty much since the beginning of the strip (Liz)?
Afterall, it would make for a good happy ending.. Jon finally gets the girl of his dreams, Liz gets Jon and gets into a home that has a couple of animals that need her attention, Garfield gets lasagna, and Odie gets.. kicked off the table.
