As much as it seems to be the popular belief, working in software/IT and the peculiarities of that culture, are not the end-all be-all of work life and workplace politics. I do not consider it at all obvious that that is what's going on. There's plenty of evidence to indicate perfectly likely monetary and business motivations for WotC.
It is just a convenient analogy, this is rife in all layers and manner of business and life. People do it all the time. Two of my friends in the last couple years have ripped out perfectly fine modern kitchens in their houses so they could do something different. As soon as you get a new boss all the perfectly good old ways of doing things get replaced by new ways. It is always at least partially NIH. Ever cat has to mark his territory.
Maybe. I personally suspect that this is a "farewell" edition of D&D that will be shelved after a relatively small run of titles. Leaving the IP to be resurrected after 10-15 years. I'm guessing that WotC has concluded that the audience's appetite for new editions is insufficient to maintain D&D as a constant, ongoing concern. Of course, if Next succeeds in its goals of unifying the audience, then WotC have the option to continue cranking out as much product as is profitable. I think the "unification" goals are an attempt to ensure that there still is an audience about 12 years from now for which to write 6e. In this, I will be happy to be wrong.
Well, I personally seriously doubt WotC would take the hit of selling nothing but low volume reprints for 2 years just so they could toss out a throwaway product.
No, this is a very different thing. Imagine you are Mike Mearls man. ONCE IN YOUR LIFE you get to frigging redesign D&D and make it any way you want. Like hell you're going to pass that up. There's no logic of any sort on the face of the Earth that would swerve any of us from rewriting the whole game from the ground up. It would be like the astronaut equivalent of being offered the chance to be to the first man to set foot on Mars and turning it down. THAT is what this is about, PURE AND SIMPLE.
I know Mike wouldn't put it that way and he's got plenty of reasons all lined up in his head for why he HAS to try to write his name in letters 100' tall across the biggest landmark in the gaming industry, but lets be real here.
Maybe you can't have all the benefits?
Seriously.
A lot of us, myself included, have been enamored of unified mechanics. Maybe they aren't the best. Perhaps there's a middle ground between 2e's hot mess and 4e's strict conformity (hopefully one with less fiddly bits than 3e, AFAIC.) Certainly a great many people who were turned off by 4e cited that as a reason (and something similar can be said for 2e).
At this point, I'm willing to accept that my desire for an "elegant" unified system is not the best architecture for D&D. It seems to work well for some of the other systems I like, particularly more Narrative-oriented ones. However, it doesn't seem to create that mystical magical feeling of "D&D." Why? I have no idea.
I'm certainly not suggesting that we go back to AD&D, where there were several different ways to "hide" depending on how, who, where, and when they were doing it. However, I don't think its totally unreasonable or unworkable to suggest and test a system where martial maneuvers work differently than spells.
You're telling me you can't tack other subsystems onto 4e? Or more properly if you have the leeway to rewrite 4e to whatever extent you couldn't fit into it a whole crapload of other subsystems? Really?
I mean ultimately this is one of those unanswerable questions and unending debates. I just don't hold with your proposition. I mean we could discuss endlessly the way this would be done and how well it would work, etc. but without being able to actually put it out there as a release of D&D and see what happened it is all just academic. That's cool though, I understand where you're coming from.

I'm not sure who or what you're referring to here. You're grammar isn't parsing for me, but maybe its because I don't have the antecedents you think I do.
Sorry, Ryan Dancy, whom you can of course peruse the opinions of right here on our most favoritest RPG site

He's certainly in the "more editions just make it worse" camp and may well have the best perspective on the whole thing going these days. He certainly knows a LOT about it, and he's a sharp cookie (maybe a little cocky, maybe, but his knowledge of the industry certainly dwarfs mine).
