Capcom said that they would be reusing old puzzle mechanics. Though the bubble puzzle is starting relatively the same, it'll probably last longer, be more treacherous, and even have enemies on the way up.
Also, the graphics are supposed to be on par with MM2, which is their main inspiration for this game. Why do so many people care so much about graphics. Platformers especially don't need fancy effects.
Now this is awesome. Thank god it's on the PSN though as the PS3 controller has the best D-pad by far (Wii on is so tiny... and yes I know you can buy a "classic" controller but they don't hold nicely).
It is odd though how some of the more nicer graphics of the later MM NES games have not been used, though to be honest who really cares? And Splash Woman? Woman? Can't say I saw that every happening in a "NES" MegaMan game. Now they just need to make a limited edition NES cartridge for it! Which brings up a point, is this a NES game being made and emulated or simply a game in the style of a NES game? And will the NES's restrictions be used?
According to an interview I read somewhere it is a game in the style of the NES games (Mega Man 2) with the restrictions as close as possible. Then again on another place that I go to most people condemned this as being a ROM hack which doesn't look too farfetched.
Don't forget the mockup boxart of this game too:

Some of the effects they use (example: detailed physics in the swinging platform segment shown in the trailer) are more than NES could handle. Besides, the game will probably end up being larger than a NES cartridge could hold.
