Via The Gamer Dome we learn that WotC has decided to emphasize their focus on Magic: the Gathering and D&D, and this new direction means the death of Gleemax. I doubt there will be too many tears shed over the demise of the lime green brain-inna-jar. However, I imagine there will be much speculation as to what this means about WotC. It'd be easy to think this means that 4e didn't sell as well as projected, or that the company is in dire straits for one reason or another.
I think this is premature. Keep in mind that WotC got a new president just before 4e was released. New presidents like to put their stamp on a company and shake things up, so everyone knows there's new management, with new ideas, and that things will change. "Refocusing on core competencies" is a hoary old arrow in the quiver of incoming presidents and the like.
