According to the first post's split I would probably rate as a "hardcore" RPGer, but I would emphasise the "RPGer" rather than "D&Der". I don't really have a single game that is "my game"; it's more like I have a portfolio of games I will play, GMs I will play with and games I am interested in running/keen to run. Each game in my portfolio I value for specific properties; if, in my view, a game comes along that does specific things better than one already in my portfolio - or does something nothing in my current portfolio already does - then it will get added to the portfolio. Games that don't do something well I might play - in particular if a GM I know to be capable is running it - but won't be on the list for me to run.
The upshot of this is that 4e will remain on my list of "to run" games until DDN (seems unlikely) or some other game comes along that does what 4e does, only better. DDN itself will be added to the portfolio if it does something well - either something no other game in my portfolio does or something DDN just does better than the current portfolio candidate. If DDN doesn't do anything I want in a game better than what I already have, then it won't make my list of "to run" games, but I might play it (if someone capable is offering to run it when it fits my diary for me to play).
