nintendo is shipping a boatload more units than sony, and they're way ahead of schedule on unit production, so the second shipment will be following soon i imagine. There will definitely not be a shortage of wii units
no, especially if you don't live in a city. The Target near me is getting like 26 Wii's and I guarantee there won't even be 26 people waiting in line for one in the morning much less camping out waiting. Wii production isn't as limited.
if you put together a good bundle (2 good games and an extra controller), i dont why you wont make a small profit, like 100-200 bucks near the holiday season
