The original Donkey Kong Country sold 9 million. I expect the new version to have a similar if not larger impact because it's returning to the roots of the original, most successful game. People will recognize this, just like they recognized it with New Super Mario Bros, and return to the series.
It's also important to note that New Super Mario Bros fans will be looking for similar content that both Donkey Kong and Kirby provide. That's a huge install base of 15-16 million.
As for Vitality Sensor, Nintendo said they would find another, more relaxing event to reveal it at. My thinking is that they will release it this year in Japan (this is why Wii Party came out early in Japan), and everywhere else in May.
