Going back to the OP's statement: in a way it's true, but for me personally, the main difference is that I found the original D&D Next play material interesting (I didn't really participate in the test, but read some of it afterwards), because the goal of 5e to be a new, shared home for the D&D community no matter what edition they played resonated with me, as did the early 5e books. Now with late 5e and the direction WotC has taken, it feels like the game is moving away from what I enjoy rather than towards it. So the excitement is rather dimmed, and I suppose that I am more likely to enter late stage grognardism for D&D in the same way it happened with Shadowrun after the 3e->4I'e transition.
(no reason to go sabotage the playtest surveys, though - there's clearly a lot of people enjoying 5e and 5.5e, so why not just let them have fun)
