Well IGN's hands on with sports champions was pretty positive.
"That said, Sports Champions actually looks pretty cool. The Gladiator Duel is more robust than the foam sword battle on the Wii. The Move controllers are extremely responsive. Every attack I tried -- a simple swing, a backhand leg sweep, an overheard smash, a lunge -- worked great. What really makes the experience different though is the second Move controller that acts as a shield. I was able to block attacks and parry."
"Watching other people play the game I was able to notice that the motion controls are not well masked fakes. People who barely swung their arm saw their character limply swing his mallet, resulting in an easily blocked, or low scoring hit. You really have to get into it to play the game. Doing huge hits when an opponent is stunned or nearly knocked out will send them flying, and I was able to hit my opponent clear out of the ring and into some columns, which were destroyed by her airborne corpse. Yeah, I said her, the game lets you brutally beat the crap out of ladies."
"The two controllers makes the game feel different, and opens the gameplay up to have things the Wii version can't do. In addition the game recognizes when the controller is behind your back, which is something I haven't seen before."
