It seems some prices have been leaked, so here we go.

The Wiiu will have different bundles:
$249.99
$299.99
$349.99

The games will go up to $60

The gamepad/tablet is rumored to be $50-$70

That is much cheaper than I thought for the Wiiu. I was expecting $350 for the normal version. I'll wait a year or so before deciding to buy one. I learned my lesson with my 3DS.
