While I haven't seen it for myself, sources tell me that the latest installment of CoroCoro offers no announcement of any new Rockman title; simply just secret boss info and such for Ryuusei no Rockman 3. Furthermore, no such promise is given for the next issue's coverage - it only states that it will discuss the Ryuusei no Rockman series. So, it looks like a bit more waiting until CoroCoro, or perhaps another source, lets us in on this new MM game in the works. We may even have to wait for CoroCoro to announce the winner of the boss character contest, which is April. We'll see.
