People always ask for multiplayer in Punch-Out and I don't see how that would work.  Punch-Out isn't really a boxing game.  It's a really a boss rush.  Every boss has a pattern and you have to dodge when needed and attack when there's an opening.  Is it really that different than a typical shmup boss?
So how do you do that with two players?  I can think of ways to have two player boxing but not resembling Punch-Out style gameplay.
I'm happy to see this franchise back.  Though I want to see a screenshot of a new character.  Maybe I'm being paranoid but I get suspicious of a remake if all I see are pre-existing characters.  They're all from the first Punch-Out too, no Super Punch-Out exclusive characters.
