I voted "no qualifier". Mainly because it gives everyone something new to complain about and argue over.
Also, I'd like to see there be a D&D core book that has the very fundamental basics and then EVERYTHING after that be "AD&D", as in it advances the system through modular additions. I think this is a vitally important marketing point. Doing it this way, they can focus on pushing nothing but the D&D core game. Literally forget about advertising anything else and put tons of money and legwork into promoting the core brand. People pick up the advanced rules without any need to advertise them beyond the website and a press release anyway.
This has several fundamentally important aspects inherent within the concept that are desperately needed to fuel the brand. First of all, it promotes ONE version of the game and everything else is considered an add-on of the player's choice. Calling all the new rules in 3.x 'core' was a huge mistake that was then taken to the extreme in 4e and was an underlying reason behind much of the backlash.
Second, it gives everyone an easy avenue to promote the game. Word of mouth and being introduced to the game via friends is a HUGE part of D&D and this has been severely curtailed by the divisions within the hobby. If we all share one common basic source that can be adapted after the fact, then we can all promote that one core product, regardless of our personal fetishes.
Third, it focuses the brand so that consumers know what to look for, what to ask for, what to investigate and gives them a recognisable icon to focus THEIR attention on. D&D has suffered over the years from a large amount of confusing products lines. New people are bewildered by their options. Introducing ONE game to them that later on can be modified as they wish based on their understanding of the game, is incredibly important in gaining new players to the hobby. DDI is great, but the amount of times I've had people stare blankly at me when faced with all their options, even with an Essentials character, makes this a prominent factor in people's take-up, in my opinion.
One D&D to rule them all; and a billion modular Advanced additions to divide and conquer them after the fact
