I don't think that "I have no interest in 5e" is an ultimatum. It just means that what has been shown to the general public is conceptual and vague. You got some folks who have played various versions or concepts of the game at private NDA bound playtests, you've got Monte firing potshots at random themes and ideas with silly polls that seem have a negative reception because they lack clarity. And finally you have the idea of bridging all the fans of various editions together to play one game to rule them all at the same table. Seems like they are shooting at the moon during the day.
I have to say its very intriguing to say the least, but its hard to get excited about colored puffs of smoke. Especially when there is no customer demand for 5e IMO. There is a WOTC need for a 5e, but I don't think the customers really NEED or even necessarily WANT it. Oldschool players have new products, 3.x players have new products, 2e players have new products, and 4e players have new products. So 5th edition is a product of WOTC's owners fiscal needs, not really because the hobby is stagnant and needs a new choice. I understand fiscal needs. I have them and every successful company I have ever done business lives by them, so I don't begrudge WOTC the right to make decisions based on them. But if you take WOTCs business needs out of the equation 5th edition doesn't make much sense to me in its timing.
But in the end I have been shown nothing to capture and HOLD my interest with 5e so far. So my general stance is hopeful but kind of unimpressed by the process so far. I have been shown concepts and ideas and I have pondered and discussed them with my peers and will likely continue to do so. I see a community broken up into pods of folks that all have a version of the game they love that is currently being supported in some way or another being told by WOTC "hey we have something new and its got some stuff that is really going to make you happy". When the pods say "cool tell me more Dr. WOTC", they get "Soon". Soon as presentation of whats to come really only works in a vacuum where the are no other options or those options suck. I think everyone playing D&D or a variant has access to fresh takes and currently supported options. So "soon" just doesn't cut the cheese all by it self for very long.
I think they need to go ahead and open the gates a little bit and let out some of that information into the wild if they want to generate lasting interest. It becomes increasingly hard to be amped about the upcoming when I like the current a great deal and the upcoming is being presented in smoke and mirrors. That being said even though I currently lack enthusiasm and interest in the way 5e has been presented to me thus far, I remain interested in the concept of 5e and check for new information several times a week. I understand they are being careful and rightly so IMO, but so far the public has really been shown nothing.
I think in the end OP you have a lot of folks who have no interest in what has been shown so far, which isnt much. What little we have been shown most of us already have access to. 5e is going to be a hard sell for WOTC because of this. Take your 3e and 4e crowds for example; why would a member of either of those groups get excited about a purposed game that compromises with the design style they do not like when they have new fresh options being made for an edition/flavor that supports everything they like with no compromises? This applies to any group of players who have a strong preference in current/previous edition especially when there are hot of the press products that strictly support the styles and desires of those editions SPECIFICALLY.
So don't get the undergarments twisted up just yet. I think we will see the real levels of interest when we start to see the data from WOTC. This edition they won't be enjoying the "Only Show in Town" status that inflated all of their previous editions initial sales(3e/4e). They have to actually generate interest this time around, and successfully market and sell their game. And the game has to stand on its own, as the definition of D&D in the mindshare of the fans has grown to include other offerings from other companies. So its no longer "man Im playing this OTHER game but there is a new edition of D&D coming out I should check that out for the nostalgia, I mean I liked D&D before edition x" but rather "Im playing a version of D&D not published by WOTC, and there is a new WOTC version coming out. Hmm Ill take a peep but if it doesn't give me all the nostalgia and happy that my current D&D fix is giving me, then i'm gonna pass"
What we are seeing is not a disinterest in D&D but rather focused interest in certain types of D&D and a lack of information on whether or not WOTC's new offering will meet the expectations being currently set by those sub-markets and the companies that cater to them. This will all change for weal or woe when WOTC quits talking big picture and starts in with the minutiae. How about those public playtests?
Sorry for the long post.
