seems like more and more ppl getting confuse bout this all region stuff. hmm ...hope some one can post the front page on how all these region stuff works. 

If you manage to get a CE in future (and subject to change FUTURE ma! ), the current way is to add the CE's CD key into your existing Bnet account that you are using for the Standard edition.

Then, call Blizzard helpline and tell them u upgrade ur SE to CE.
They will give u a new SE CD Key then.

The CE upgrade then call Blizz is confirmed by Bashiok (Community Manager) previously.

could anyone with beta key confirm this? if you kill a monster and the item drops on the floor.. then you pull the plug.

will..

1) the item lost forever.

2) the item goes into your stash.

All gone...

i think SEA and US RMAH is the same..

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/

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.

make it simple,SEA RMAH does not exist,so that why all join US RMAH.
SEA SERVER does not exist,,so that why all join US SERVER.
