I think things would’ve worked out differently if Nintendo hadn’t messed up the naming of the Wii U. We probably would’ve had a line up like this:
• Wii
• Wii Pro (Wii U)
• Wii Portable (Switch)
They’re at that crossroad again with the Switch name. What do you think the Switch successor should be called? Keep the Switch name or nah?
I’m not entirely sure I agree the Wii U was an iteration on the Wii. Name aside, they played very differently from one another. I think Switch is closer to being an iteration on Wii U than Wii U on Wii.
That said - the rest of your points are pretty good. They basically had no choice but to make drastic changes on the N64, and the giant change from the GameCube to the Wii was a change in strategy as a reaction to failure. Plus the points about the handhelds.
I’m cautiously optimistic the next console will just be a better Switch, but I definitely wouldn’t bet my pinky toe on it just yet.
