So what of us who wants the annual pass + CE + Box?
If I commit to annual pass, I get a DIGITAL version of Diablo 3.
I can later upgrade this, assuming from website, to a digital CE. No box
However if I buy the Collectors Edition with box from a store, I'll have 2 Diablo accounts.
Note that if it is possible to use the store bought CE key to upgrade the digital D3, it would result in a loss.
As I'd only get 4 months extra WoW time by upgrading, but it'd result in me essentially buying 2 diablo keys, but turning it into 1. Resulting in me not actually gaining anything by doing the annual pass. Except for vanity items in WoW. And I lose out on D3 box.
