Mike Mearls said stuff on Reddit.
Regarding the 5e DMG that's coming out in about a month:
"There are rules for domains and managing a realm or business as part of the downtime system."
That's good news. I think that experiencing the characters go from murder-hobos desperate for gold to movers and shakers in what is really a totally different game is a big part of the draw and what makes rpgs a unique thing. Also kender will not be in the DMG which is really really good news.
"Here's what I'd do if I designed the game solely for myself.
More dice, fewer static modifiers. I'd use a die in place of the proficiency bonus. I like rolling dice and find it easier to teach that way."
The person asking the question clarifies: Replacing a +2 with a d4, +3 with d6, +4 with d8, +6 with d12, etc. That sounds FUN. Doesn't DCC do something like that?
"I wish the MM could be an app rather than a book. Working in page counts sucks, to be honest. I would've loved to break out tables of bonds, traits, and flaws for every intelligent creature in the game. Don't get me wrong, I love physical books, but on the digital front there's so much potential in breaking out of physical restraints."
This sounds cool, but I feel pretty sure WotC would do it all wrong. I want to see a They Stalk the Underworld app, that would be awesome. and there could be links to things like John the Retired Adventurer's Wandering Monsters Lair/Spoor/Tracks/Traces.
Somebody asked: "Will we see Dungeon and Dragon magazine again? Will there be digital content on the website, similar to the maps, art, and adventures we saw in the 3E era?"
and Mike said:
"We're exploring options for the magazines right now. Nothing to announce yet, but we know they're an important part of D&D's history. That said, the magazine business is in rough shape. Subscriptions to them were dropping heavily in their last years in print, and that was six years ago. You can expect anything we do will be delivered digitally."
I'm still holding out for the D&D Mega-Blog. Only WotC could do it, and it would be a reinvention of the magazine.
