Funny, I like the new products because I have what I think of as the old school mentality of making use of whatever I can get my hands on and incorporating or adapting it to varying degrees. Not everything TSR made was to my tastes, just like not everything WotC makes is to my tastes - but with both I look, I take what I want and I leave the rest - sometimes that might mean going a year without a new book even if they're printing a ton (that also happened in the 90s) - but that's okay, there is still plenty to look through and re-discover and make use of. That might also mean skipping editions (I skipped 4th and only incorporated a handful of stuff from 3.5 into my 3E game). That might also mean incorporating rules and approaches from other systems entirely. Who knows?
To me that is the fun of GMing when not immediately running a game.
