Nintendo is probably getting the Tegra chips for dirt, dirt cheap because Nvidia hasn't been able to find any vendors for the chips in traditional tablets/phones, so Nintendo was probably like their last resort.
The chip itself probably doesn't cost much at all, the Nvidia Shield console is $199.99 with the Tegra X1, and that was *two years ago* by the time March 2017 rolls around.
$299.99 = Basic NX
$99-$129.99 extra = Home Console Dock with second Tegra NX Processor
Sounds reasonable enough.
