Probably in the next few days. Im guessing he wanted to wait for the months payment to end for his subscribestar fans so they didn't feel like they got cheated out of their money by having the access drop early? Or mabye just taking time off to celebrate the holidays.
I feel you man, I've been waiting for this update for sense it was first announced and im dying of anticipation.
But he does do this for free so ill be happy when ever it comes out :)
