They won’t do that, i think , because they don’t have the same publisher for online and box versions .
if it’s available online before the box version is , they won’t sell much of those.
What they could do , is to give access to the beta to those who pre-ordered the game , let’s say , before today .
Those sales are already made , and it won’t affect which versions people choose .
But i think we’ll have to wait until the official release …
