Just a taught, When Mists of Pandaria was digital Available, that was 2 months before MoP went out.
Let's say we still gotta wait around a month till WoD gets into beta, Blizzard already publicly announced that the digital purchase will be available soon.
If we look at last expansion's pre-order and launch date, we got 3 month's max left till WoD going live.
Am i thinking to much over nothing, Or do you think this is possible?
2/3months of beta might sound short, but who knows.
