I am not aware of one available since the second edition and the negative one came out. And both are sold out.
Here's Masa's store:

It just says there will be a 3rd edition, not when. You know as much as anyone here ! You could email and ask.
Masa made a post on his Facebook page on Christmas Day 2016, saying that the ST 3rd edition will take about 3 to 4 months. I'm not sure whether it's to design completion or to print completion though.
