I hope they have both normal and motion controls just in case they are too stiff like Wii Sports or just broken like victorious boxers. Options please.
To me it's looking with Kaiser, Joe, Hippo from those shots, and also seeing the placement of the heart meter and the word ROUND that it could be a recreation of the original. At the least they're not going back to the broken setup of the SNES game with just one round to finish it. When they did that, then forced you to use an entirely canned script to do each battle combined with some truly cheap (spitting) or stupid (clown balls and kicking) crap I hung up the gloves.
The gameplay video that exists and the images look to me that it's back to the good setup with rounds, the ability to mix up your attacks, and some 'moderately' scripted things like popping that fat bastard hippo in the gut to win, or just brawling it out with kaiser and joe to finish it.
I'm actually psyched for this release.
