I advise a high school game club. They play it all from video games to card games to paper and pencil RPGs. The paper and pencil crew is hip deep in 3.5 D&D and d20 modern. More than half are new players, none seem to be having any great difficulty and all seem to be having a blast. They loooked over 4E and chose 3.5. The relative complexity doesn't seem to bother them. Given the rate at which WotC is cranking out books (each thinner, often subdivided, and more expensive than it's 3.5 equivalent) for 4E I suspect the complexity issue is relative. Different players will like each (or in some cases both). My own game is rolling over to Pathfinder with some house rules. It's a better fit for my homebrew campaign. I see it as a differnt balance between world simulation (3.5) and game (4E).
*edit* My campaign world originated with the original D&D game in 1974-5. Too many differences for a comfortable transition from 3.5 to 4E.
