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.
