We need itemization changes first though selling Diablo 3 account, for that to be possible, but there's hope.
lol. Man, if they are going to introduce some form of ladder in the future, they would be stupid not to think about the very limited space we have now... in other words, they will definitely expand the character space and stash space, you just worry too much, bro :o
Correct me if I'm wrong, but didn't they back down from wanting to give us more space in D2 because they would need to spend a lot of $? One would assume that this reality is true for where to buy Diablo 3 account as well. It might come with an expansion if they feel it is necessary, but it will not come from a mere patch.
In any case, I'm not in favor of a ladder reset right now... maybe after the last XPAC or something.
