It remains a tough question to answer for now. I’d say it depends on how long PS4/XBOne last and how much time of Switch’s life it competes with those. If Switch overlaps with PS4/XBOne for most of it’s (relevant) life it’s an 8th Gen console. A second entry in the 8th Gen for Nintendo, because WiiU is definitely not a 7th Gen upgrade. For one because it didn’t compete with PS360, so it isn’t 7th Gen, and it’s sales aren’t counted with Wii’s because Nintendo presented it as being a successor, so it’s not an upgrade.
In Switch’s case it’s either this or PS5/XB2 should be considered 10th Gen (along with the successor of the Switch) if they take so long to release that Switch itself nears it’s twilight years, and Sony and Microsoft simply skipped a gen. None of these things are without precedent. Obviously if Switch ends up competing with PS5/XB2 in it’s adult years they’re all 9th Gen, but we simply don’t know anyone’s plans yet. Actually Barkley’s graphic above illustrates all this quite nicely.
