January is a safe bet. There would be no point from a production perspective to do it this close to Christmas vacation. I would like to play it during the holidays, but that isn't a motivation for them. I would bet serious gift card that the random maps issue will take them the rest of the year to kick.
I totally agree. The same logic from Thanksgiving is probably at work here. Too little time, too much to do, and who wants to man the beta reponse forum for Christmas.
It's pretty clear that Derek isn't going to let the beta out until he can look Brad in the eye & say: "We've cast out the E:WOM demon sir. Even Lord Xia will be pleased once he gets done ranting about the lack of pink ponies!"
