I voted Other.
The title should be "D&D: Do or Die Edition" or "D&D: Make It or Break It"
I say this b/c if the $50M "Core Brand" target is legit (and I think it probably is), this is D&D's last chance to reach that status.
If it does, it will become a core brand with the resources & yes, the revenue requirements to hold onto that title, budget, and staffing.
If it doesn't, one of two things are likely to happen:
1. D&D suffers additional decline as budget & resources are allocated to Core Brands. D&D continues to exist in some form but in a diminished form compared to 3e or early 4e.
2. Hasbro, which doesn't sell off intellectual properties, shelves D&D for a period of time with the intent of reinventing/relaunching it down the road.
My post has little to do with the game itself, btw. The modularity talk is intriguing, although I think right now people are assigning their own meaning to the tidbits we're hearing and the final version may differ significantly from those expectations. It could be a great toolkit or a complete mess.
That said, I think where WotC screwed up was trying to establish D&D as a core brand, rather than treating WotC lines in total as the "WotC Brand" (if such an option was even possible).
This isn't the game environment when D&D launched, nor is it when we had the doldrums of 2e and the implosion of TSR where 3e was viewed with great anticipation. D&D has more competition (in both media & direct competitors) than it did in either of those earlier scenarios. It could do everything "right", and still not reach the Core Brand requirements, thus triggering one of the two scenarios I've outlined above.
Hence, D&D: Do or Die Edition.
