There is a google calendar in the OP where I list the releases almost as soon as I find out about them. If you're not averse to Discord, there are many servers out there that track these things.
There are 5,000 copies of the CE through LRG. I have no insight on the demand, so I won't speculate on how quick it will go, but I know there are a lot of folks who hate LRG, are displeased with YsNet since they backed the KS and now they have to spend more money to get the CE, and have no clue what LRG even is.
