I was delighted to read the following New York Times article this morning, in which Wizards of the Coast is in the planning stages of their envisioned reboot of the Dungeons & Dragons franchise. You can read the article here.
I can safely say I am not the least bit surprised that 4e tanked like it did, and I am definitely excited for the release of ACKS, but it will be interesting to see what WotC comes up with next.
More of my thoughts on the topic are summed up in this Escapist article.
Peace be with you, D&D 4e. ACKS is coming soon.
