At my university, of the 7 RPG groups besides mine that I've run into, 5 play 3.5, 1 plays Pathfinder, and 1 plays WHFRP, and they all say they don't know of any 4e groups on campus either. Back home, one friend's group plays 3.5 or Pathfinder depending on who's DMing, another friend's group alternates between 3.5 and SWSE, and the local game store has 1 regular 3.5 game and 1 regular Exalted game. Not a single 4e group or game in sight, not even players who have anything more positive to say about 4e than "Well, I liked a lot of the ideas going in, but it just isn't for me" or similar. My experience is probably an outlier, but take it as you will.
