4th Ed is the first time my group and I didn't switch. (Playing since AD&D v1.) And we tried it, but just didn't care for it. (We will admit to being somewhat prejudiced by the pre-launch marketing dissonance.)
Same here. Played since pre 1e days, switched to each new system at some point. Tried 4e. Disliked it a lot for various reasons and stayed with 3.5.
And we'll give the 5e rules a look. Try 'em. If they don't work for us, we'll simply keep on with what we're doing.
