Guild Wars 2

hi,
i wanna know what does that DIGITAL DELUXE UPGRADE does exactly … ?
if i buy it .. what happens ..?
do i get a new serial for making a new account ?
or i get a serial which is only works for my existing account ?
or i can choose betweeen both ???

Well the upgrade is used to upgrade your existing account. If you buy it in game, it gets added to your account and you get an email (in game) with the goodies.

So it does not buy you a new account, that’s only when you buy a normal digital deluxe version instead of the upgrade.

The word really says it all, it’s an upgrade.
