Their record was 5 or 8 years.
The rapid turnover of editions in the last decade and a half has NOT been healthy for D&D or the hobby as a whole. The 3.0 to 3.5 transition stucky hobby stores with product they could not give away, the 3e to 4e transition splintered the audience and gave rise to potent competition, and the 4e to 5e transition gave rise to a wealth of smaller games and direct competition.
Changes are hard on the dwindling number of game stores and hard on the already small audience, and they make it awkward to get into the game by increasing the likelyhood of getting into the hobby immediately before an edition change.
And has it made D&D healthier and more successful? No. The D&D team at WotC has shrunk every year, whether by layoffs or not replacing outgoing employees.
Rapid edition changes have not worked in D&D's favour. Continuing short editions would be a mistake.
What I think we'll get:
- A big campaign book every year.
- A revised 5.5e edition in 2017.
- A new 6e edition in 2020.
I don't expect to see any splat book or setting book.
Im hoping to see a 5.5 or 6th edition that one of the major changes is a starting feat for everyone. Im starting to houserule that now and early levels are going alot better.
A smaller team could work in their favour here...large teams are sustained by a high volume of releases which quickly saturates the edition and fatigues the player-base. Maybe the plan is, keep it lean, keep 'em keen?Preaching to the converted I just doubt they could do a 10 year edition.
