One game switched and we like it so far.
One game still running 3.5, no interest in 4e. Since I am DMing it and they want to go through Savage Tide AP I have stated that the only way I will run that is 3.5 Core only (with few exceptions) or Pathfinder. Likely someone else will run the game for a bit which is fine after 2 years of DMing Age of Worms with one year to go.
One game is totally new 4E campaign with new or returning have not played since 1E group. They seem to be enjoying the game.
Oh, and our monthly FLGS meetups are 90% 4E, with one pathfinder and one 3.5 game running each month.
