I have a strong feeling that this thing will end up the same way as the first Wii did.\
A crap load of people will rush out to get one,play it for a few weeks,realize that the novelty isn't really all that it's cracked up to be,then it will collect a 2 inch thick coating of dust.
You would've thought that one of the first games that they would develop for it would be a Metroid game,but seems like they are already dropping the ball on that opportunity.
