I would promise a new game and release a new logo along with it. Then I'd wait 10 years then tell the world I'm closing the company.
Not really.
I'd re-release AO/AE and put them on Xbox Live Marketplace/PSN, and add some bonus levels to go with it.
Then, I'd remake Munch's Oddysee, with a minor graphic update, bug fixes, put what was removed back in, and other stuff, and release it on XBL Marketplace/PSN/Steam. I'd do the same with SW, but it doesn't need remaking 'cuz it's fine how it is.
And while the fans are happy with what's happened, I'd continue making the new Oddworld game.
