So, at some point, all next-related threads come to that same conclusion that, no matter how successful the game is, 6E will still be here sooner than we want it to...
Actually, I've seen surprisingly few references to 6e for the past year or so.
because WotC business is based in selling core rulebooks...
and I'm pretty sure this is outdated as well. It's actually not entirely clear what WotC's strategy for 5e is, but for the past few years they've made a huge amount of money from DDI subscriptions. Indeed, they're
still making lots of money from DDI subscriptions, which is probably why D&D can almost stop producing new materials and not be cancelled.
I don't want to buy new D&D editions every year from WotC, but if they release one solid game every year or two, I see myself buying them most of the time, because I like having different games to play and I'd love to have more than D&D from WotC, because I really believe they have talented folks there whose ideas are worth my money. I don't need a D&D brand in every product I purchase from WotC; I love Star Wars Saga and d20 Modern, for example, and I'm ready for even more unusual offers.
The next problem is this: Core Rulebooks
with the D&D logo sell better than anything else. It's worth noting that "d20 Modern" never got a new edition, despite being ripe for one. The "Star Wars" license was allowed to lapse. The new "Gamma World" had to be sold under the D&D brand, and did well enough that WotC never quite did another not-quite-D&D game in the same vein.
and before someone says that those games would compete with D&D and cause further damage to our community, we must remember that the market for non-D&D games is already here and thriving, WotC simply decided, up to this moment, to not make a profit from it.
Define "thriving". Because Hasbro have requirements of their various properties, that D&D can
just about meet, and it appears that no other RPG can.
I'm sorry to pour cold water on your suggestion, but I'm afraid that that's the reality that we're dealing with. If it's not
huge, Hasbro just aren't interested.
