Will the next set of COS Pottermore chapters be released July 20th?

After the first four chapters of Chamber of Secrets were released on Pottermore, we were told that the second of three sets of chapters would be released very shortly, however no time frame was specifically given to us fans.

My favorite theory is July 20th, though I feel like if they are breaking it into sections, they may be trying to spread the releases much further apart, possibly even a month between each release. Anyway, the reason July 20th sounds interesting is because we may have been given a clue already within the first four chapters! If you navigate to Chapter 3, moment #2 "The Burrow", you can see that the license plate on the car is labeled "COS 207". COS most likely stands for Chamber of Secrets, and 207 could represent 20/7 - or the 20th of July. Of course this could mean many things, or it could mean nothing at all. Maybe it means something else that might of importance, but not the release date.

I guess we'll just have to wait to find out.
