Megaman 9 was made by Inti Creates, which did MMZ and MMZX series.
So, i think they was mainly busy with MM9.
However...
There is always this to wait for.

"Nintendo Dream's Announcement Concerns a New Series?
Allan "Nicol" Montenegro of Taizen Saint Seiya, has attempted to translate the blurred text from the mysterious Nintendo Dream announcement:
Top text: "Burning/hot/ardent battle"
Lower Text: "The newest series! At long last the work..."
Is Nintendo Dream implying the coming of a new series? Perhaps, but then what's the "at long last the work" all about? Whatever it is, sounds as if its been in production for a while...
I really don't know what to make of this one, too little to speculate on. Your thoughts?
