As for the crunchy books-
I only bought the PHB1/2 and MM1/2. So it doesn't really bother me what WOTC continues to pump out on that front. If players want to use XYZ Power-they can buy the book and get it approved (or not) by me.
I'm not falling into the 3E trap of feeling the need to constantly buy more and more and more splats. The only "rule books" I plan on picking up are DMG2, MM3, and I'll likely grab the red box/essentials line just for fun
I think the direction WOTC has gone down, and is going down is great.
I don't mean to sound like a fanboy but I've been super happy and excited with the revamp to the D&D line/business. They seem to be catering to my tastes and needs. I did not care for the late 2E/3E era of WOTC on the whole- the products-the design philosophy, the magazines, etc etc.
