I`m sure some of you are collector edition users for wow

I preordered me some collecter editions for cataclysm but I`m also pretty excited about the news about the digital upgrade + instant midnight play(taking some days off).

However the collecter editions will only arive somewhere during the day of 7dec.

Anyone, who has experience with the old CE`s can tell me if I can still make the online upgraded account into a collector one? (as in pet and feat)
