No, I'm not sick of it. I can easily skip threads with subjects I have no interest in. I only occasionally check 4e threads, when someone whose word carries weight either makes it or posts to it.
As for WotC wanting to make money off of it...well, duh. They want to draw a paycheck, don't they? Who here goes to work purely for the love of what they do, refusing any and all compensation? Regarding what needs to be changed about the game...well, I actually like 3.5. I hope any changes the game goes through are not all-encompassing. Stuff like the new stat block format, the changes to polymorph, and Mike Mearls's recent redevelopment of classic monsters seems in line with the kinds of changes that would be palatable to me. If we're talking about really radical changes - getting rid of classes, for example - then no, I'd rather not have that.
