The last time we got this pep talk, they launched a new edition, I don't think 5e is coming, but something is.
Thunderfoot's post really has me wondering. I went and re-read the original article. It starts out saying how players want to know where the game is going in the future and then spends the entire discussion talking about the past & the experience of D&D. So, the future really isn't discussed at all. Clearly, this is something that is going to be built up to over some period of time.
While re-reading, I ran across the link to the second article in the series and the topic is... MINIATURES?!?
I have no axe to grind with miniatures. Sometimes I use them, sometimes I don't. What I find odd is that Mr. Mearls chooses this topic in light of the current fate of the D&D Miniatures. Is it salt in the wound for some or a set-up for hyping the VTT?
I'm really not sure what the objective of these articles are. (That's a speculative statement, not a judgement so turn the burners on the flame-throwers down...) Make no mistake, however, there is an objective. This isn't Mearls' personal blog. He's writing in an official WotC capacity and while I can't see the picture yet, I think there's an underlying purpose to it all.
I just can't determine if it's intended to be 1) a marketing campaign disguised as gamer musings (harmless), 2) an attempt at improving/repairing WotC-gamer relations (commendable), or 3) a slow build to a major shake-up of some sort. If it's the latter, I think that at best, we'll see a risky (in WotC's view) change in business plan, and at worst a "disruptive announcement" (like a new edition, new lawsuit, price hike, new owner, etc.).
My SWAG is just that, a guess, but I tend to think it's #1 or #3 as those are more readily tied to an measurable business goal/objective. The fact that the 2nd article is about miniatures when they recently pulled back/dumped a miniatures line has me thinking Scenario #3 is the most likely.
So, maybe it's as simple as "Hey Mike, can you write a regular column for us about D&D?". If so, then I spend way too much time at ENWorld & conspiracy-think has taken hold. However, if it's more than that, I'm hoping for #1 but betting on #3.
YMMV.
