For me, personally, I'm not moving to 4e (though I may buy a few 4e supplements if they are easily compatible for 3.5e). I have almost every 3.5e (and many 3e) supplements and I'm currently stockpiling adventures, including every 3.5e issue of Dungeon. Between all of that material, my own stuff, and any OGL, I'm set pretty much for life.
