This is what the patch is really all about.
IMHO The thing is B-net waited too long to do anything about the dupes and hacks stuff.
Right now, hex charms, dupe runes and all the other hacks stuff and dupe stuff is the thing people use for trading. Meaning that removing all hack/dupe stuff right now, a lot of people would whine like hell about it saying "but I traded my legit WF for those hex charms". If b-net had it their way and I repeat their way.....they would love to erase the server and make everyone start from scratch. But we all know what would happened if B-net did that....MAJOR whining and bitching from the public.
Therefore, making the new patch, everyone starts with nothing. No one will have 3 mules fulls of SOJ, hack stuff, dupe stuff, etc. Everyone will be on an even playing field.
But the million dollar question, why would anyone play with the new patch...for the hell of it. B-net has to give everyone some sort of incentive to do so. Add more weapons. new bells and whistle, Every other day...b-net tease everyone with a new screen shot from their web site. Make most people here WANT to play with the new patch, and in return, bring back D2 economy. Everything is just my opinion, but this is what I believe B-Net is hoping for.
