Sega is plenty smart when it comes to software (i.e., games). When it comes to hardware, they haven't done anything smart since the Genesis. That being said, what makes Sega REALLY smart is dropping out of the console market to concentrate on their strength, games.
It's Rock Band Network, which is the deal where anyone can author tracks for Rock Band. Buckner and/or Garcia (or whoever owns the rights to that stuff) are behind this. (I assume it's them because Pac-Man Fever kinda sounded like a re-recording.)
