I still think it's too late for the full reveal. They may well lose potential buyers thanks to it not being prior to Xmas. People will spend at Xmas whereas they may not have spent as much if they thought they'd save for Switch too.
And if the dock truly does nothing more than charge and TV out the console then no matter what Nintendo say, or their fans, this is a handheld device!
Now if the dock does do something more, a boost of power, adds memory or features, then fair enough... but until we know for certain, it's like we're calling an apple an orange just because Nintendo say it's an orange.
