I said 'almost' a Wii replacement as there are some quirks that need to be addressed like poor cut-scene video/audio sync and lack of support for Wiimote speaker. However these are reasonably minor given the benefits gained and it wouldn't surprise me if they are addressed by the next release.
Try lowering your FPS limit. I was experiencing this until I locked the FPS at 30. Depends on the game though, I'd rather have 60fps and slightly dodgy cutscene audio if it's an action game.
