There is a preview up on Xbox Live's Inside Xbox or Spotlight. Shows a lot of gameplay footage. The camera moves around the characters a little bit more. The punching is definitely improved, but I still find some of the punches to lack the impact they should have. Some of them look great, and the overhand or looping punches should add some interest angles for attack. Whether it really affects gameplay, I don't know, since the blocking is one button now, instead of directional. The knockdowns are handled the same way as in round 4, where you have to use one stick to keep steady and the other to stand up. Looks like you can be a fatty again, because Butterbean is sadly in the game. They did have a clip of Lennox Lewis KOing him, which was nice to see. Gameplay looks very fast, and the graphics look NICE. Overall, it looks like they refined the physics and the visuals quite a bit, so it really comes down to how well the new gameplay mechanics work. I watched the preview with the audio off because I was listening to records, so there may have been some other information tidbits I missed. Not sure if the preview is up anywhere else.
I'd also like to add that the visuals were surprisingly not far off from the screenshots they've been releasing. I'm sure there are some differences in anti-aliasing, but the gameplay footage looked very clean. I'm guessing 720p 4x MSAA like Round 4 and EA MMA during gameplay. I imagine it may have some replay enhancements like EA MMA, but the footage was game play, not replay.
