===============+================

When Diablo III is released, it will have no specific assigned region. The only thing that will determine which store you're purchasing from is which location is easiest to ship from. Thus, no matter where you get your copy of Diablo III, you will have access to any regional Auction House at any given time.

For more information and updates on Diablo III, please visit our website! http://us.blizzard.com/en-us/games/d3/

Emailed GM to check , GM says you will have access to any regional auction house . Still not yet 100 % confirmed , but should be pretty clear now 

That's incorrect. The GM was appearing to answer from WHERE you BUY D3.
And it is not answering regarding AH at all other than you have access to the "regional AH" which we already know.

EDIT: It'll be better to wait for the official announcement as the GMs can give incorrect answers for something that hasn't been released directly by the dev team.

"You will have access to the regional AH at any given time" but then how is it going to explain this then?:

http://us.battle.net/d3/en/forum/topic/4175551303
How does this impact the items I have purchased in the auction house?
Auction house purchases are bound to the servers in the region in which they're bought. Any items acquired on game servers in the Americas region are bound to those servers and are not transferrable to the servers in Europe or Asia (and vice versa). Please keep this in mind when making purchases in the auction house. We’ll release more details on the auction house functionality prior to the game’s release.
If you have access to any regional AH, you should be playing in that region.
So if you're playing in US server, you can buy from EU AH?
Doesn't make sense right?

Yup like i said it's not 100% confirmed yet  . Mayb what he trying to say is the lock applies to items bought or sold via RMAH. For example, if you buy from US auction house, you cannot sell in Brazil auction house. You can only sell it in the US auction house , but you can access any region's RMAH .

Let's wait for official press release then on this issue sigh  .

i dont see the issue here. if you're from US of course you buy from US AH, but you also can buy the item from EU AH but it will only be available to your character at EU AH. they are giving you option to region hop when you feel US is not for you, or you want to join your friends at asia region. pov though.

Agreed it'll be best to wait for official word.
For all we know, what's true right now can even be changed the last minute before launch (or even after that)

However, accessing different region's AH seems weird.
It seems you can then go "shopping" in different AH for best price then

Then Korea can also region hop to other AH

hmm you have your point. lets wait then. its blizzard. anything can be changed in the last min the game release

The AH system has been fix ages ago. Its just that people are making it very confusing, with different information.

Blizzard has stated this many times.

You will have access to all servers no matter which version of Game you buy.

The RMAH and GAH are all region fix meaning to say you cannot buy from US RMAH/GAH and send to EU toon or vice versa.

RMAH is only available to your home region. However GAH is not fix by this rule. Meaning, for us we are fixed to US region, so we only have access to US RMAH. We will not have access to EU RMAH. But we can make a toon on the EU servers and use the GAH.

So what is so confusing about this???

Applies to non-Korean or those that countries that did not banned RMAH:
1. You can play in whichever region you like (Asians default to US but can change).
2. You play in what region server, you use that regions' RMAH and pay the $ using EDIT:their that region's currency.
