The Wii U is 8th Gen regardless of it's spec. I thought this was established -_-

When you need add the bolded it voids the underlined.

I thought gen is defined by time, not by how powerful a console is. If that were the case, then surely Wii and GC are in the same generation implying the Nintendo have either fallen behind or missed an entire generation.
