Relax! I really don't see any problem with this sort of discussion - From my perspective this isn't about overpowered/underpowered or anything like that, but merely value - somethings are very expensive, and worth every penny when they're needed, but somethings aren't neccesarily expensive while providing a lot of utility - like a pocket knife on a camping trip.
And if you really want to convince WOTC not to come out with version 4.0 - stop buying 3.5, stop talking about it (at all, not just "munchkin items" and crap like that whatever you think that means), stop playing it, and mostly just find another hobby. As long as people will buy it, they will come out with new things to sell - that's not evil, it's just business - they're a company, their whole point is to make money, of course they're going to do that. If you don't have anything constructive to add to the discussion, just leave it alone and please find another, more appropriate, thread to pollute with your paranoid rants!
