Looking at the pattern in the last few patches I'm guessing we will see 1.21 bumped from early February to mid February for balance adjustments and whatnot. While I'm super excited for the patch, at the same time I would rather it be a good working patch and not rushed out to meet a deadline.
The good news is that they have really been on the ball with at most a week delay in the patch, (not too bad really). That being said, and not knowing their development cycle I can't say if 1.20b is going to delay 1.21, but it might to some degree.
I guess the trick is to enjoy the game as best you can, look forward to the future, and try to not let delays effect you. It will arrive when it does, and hopefully we'll start to get that information shortly. :)
