I would love to see these guy tackle upgrading and enhancing two games specifically after completing this trilogy.....if they were interested enough of course. I wouldn't expect it, but it would be interesting to see Mega Man V from the Game Boy, and a lesser known more obscure title and sequel from the Wonderswan titled Mega Man & Bass Challenger from the Future. I could easily see the Wonderswan title being remade in the Mega Man 7 styling, and with how these guys improve various things, I'm sure they'd make it feel more like a console Mega Man game then what it turned out to be.
Mega Man V from the Game Boy in 16 bit graphics I feel would be like almost seeing as it was meant to be. Like Capcom possibly had grander ideas for it, but for whatever reason relegated it to a handheld release that felt like it limited it a bit. Kinda hard to describe since it was the pinnacle of the handheld line of games, but it felt like it could've been more.
