Up until late 3E, I used to be a completionist. The only thing I pick up from WotC these days are the tiles, board games and maybe the one-offs like Gamma World. Maybe an occasional mini, but usually through the secodary market as I'm looking for a specific mini and don't want a bunch of random clutter. Over the last year, I think I've bought: the Red Box, Gamma World, City Tiles, Castle Ravenloft and a handful of pre-4E minis. I've gotten some use out of the minis and tiles, the rest has been glanced through and just shelved.
For the most part though, my former RPG dollars are going to trying out other RPGs or into my Pathfinder adventure subscription. Wotc's schedule doesn't have much of an impact on my buying trends any more and I no longer look forward on their production schedule with the giddy glee it used to inspire.
