A NeoGAF forum user has posted some gameplay screenshots of what is considered the final version of Might No. 9, but the results as you can see below, they are more than disappointing. Some forum users questioned the possibility that the screenshots correspond to the version of Nintendo 3DS, but this is not feasible because the images are taken in HD resolution (1280 × 720).
During last Christmas, Keiji Inafune had posted a video with a few seconds of gameplay, announcing that the content was already finished and only lacked polish some details and start making the ports of all versions. Therefore, it is likely that the pictures do not lie and below the screenshots you are seeing are legit.
The lack of anti-aliasing or poor quality added to the stage and lifeless colors really disappointing for those who are expecting a worthy successor to Megaman. Hopefully in 1080 and better anti-aliasing look better, at least in motion, and the gameplay would be good.
