By now it seems like it'll be hit around the 20th or so.
I second that

20th seems like a good date

It can be hit earlier before 20th, I think the daily rolls is around 10million in average and it will be increased in the last few days as usual. So, it should be hit around 16-18th.
Yes but everyday is different. Who knows in the USA/Canada there is a long holiday so more people will be gambling and it might be earlier.
