D&D Next has its problems. Some of this is marketing as WotC is not spreading the word too far out of the community. They're hitting people already in the loop. WotC's marketing department is terrible at spreading the word. But I doubt D&D is their priority.
I am not sure if D&D next should be too much advertised already. I believe, they did right, only trying to reach for the core of gamers until the core is finished.
You already see in the forum, that not even all forum users get the point of this stage of the playtest: trying out things until they can make the core from all previously testet packets... taking the best of them.
I guess many gamers just want a stable, polished sytem that they can play. Best if it is good.
When the core rules are set in stone (maybe some edges could be cut off later) then it will be time sharing the word. Then the whole playtest starts beeing a great marketing thing. Those players who started testing in 2012 are really drawn to the game, as they were part of the most early process.
They can possibly tell their fellow gamers:
"If I hadn´t constantly remining wotc to not mess around with the rogue, we would have the crappy thing from playtest 3... I am so glad I complained so loudly, that wizards returned more to the 2nd playtest version in their final version."
