For those of you who haven't been following along, Bandai's D-Arts toy line (which makes Mega Man toys, among others), is now collectively known as S.H. Figuarts. Their first release will be the Mega Man Zero figure, which has already started shipping in Japan.
Now, we have a firm North American release date of November. Given how all of these toys have worked previously, they'll ship out anywhere from the start of the month, and trickle out over the course of a few weeks.
Personally, I order every Mega Man figure from Amazon, so check their listings every so often.
