What edition are you playing?
Right now, we're starting a 3.5 campaign with possibly some Pathfinder add-ons; after that we'll go back to a Mutants and Masterminds campaign and after that, full Pathfinder. At this point, we will not be going to 4E; several of us have played it and feel we've given it a fair shake, but it's not our cup of tea.
For the last nine years, we've played some edition of d20 almost continuously with only brief detours to other systems.
