The big news today is that Blizzard announced that they will be removing both the Real Money Auction House and the gold Auction House on March 18, 2014. (Gee, I wonder when the expansion will be released.)
As you know, I am not a fan of the AH in D3. I still didn't think Blizzard would remove it entirely, though. Props to them for being willing to reverse course as needed. I think the major turning point was probably the release of the console version of D3, which did not have the AH. The console version has been very well received.
That being said, there are some people attacking Blizzard for putting the AH in the game in the first place. I think this is misguided. It wasn't an obvious mistake at first. The AH was put in to solve the problem of third-party scams, and by all accounts it did a very good job at that.
What I think will be most interesting is to see what measures Blizzard puts in place to stop the inevitable third party sales, scammers, and spammers. Will there be some sort of secure trading? Will trading be disabled entirely?
By and large, I believe the console version doesn't have issues with trading because you trade primarily with local players in your living room. As well, the different networks are segregated and more controlled. But I think that free trading on the PC will lead to the same problems as D2.
But perhaps that's the better outcome. The positives gained by removing the Auction House might outweigh the negatives of spammers and scams.
