I picked up the June 2007 issue of Game Informer yesterday and in it, they rated and reviewed MKA for the Nintendo Wii.

The game got an average score of 7.5, based on their system of grading. In the article itself, they go on to say that the Game, played with the Wiimote and nunchuk isn't as responsive as the previous teaser videos suggest, and that aside from the Endurance mode and training areas, the game pretty much is a direct port of the ps2/Xbox versions sans online play.
