Well.. There are tons of things we don't know yet, most importantly is the price.
But with that being said... It is a handheld that can plug into the tv. If we assume that Nintendo won't make an actual console, that means that we can probably take away the usually overlap buyers. So I say around 60-70 million at $200sh pricepoint. Anything above $200-$250 will make the handheld a lot less of an impulse buy for most people so the sales will go down as the price goes up imo.
