Despite having a long-distance release date of January 13th, 2015, the ninth Mega Man trade paperback has already been listed on Amazon.
At 104-pages, it will compile the entire "Dawn of X" storyline. As the usual pattern dictates, that's issues 37 through 40. Beyond an early 2015 release date, however, there are no other details. Expect them to bubble up as the months fly by.
