The Switch has 3 models, taking into account the different colour variations that's 7 Stock Keeping Units (SKU's) without taking into account bundles or special editions.
If Switch2 releases in 2 colour variations again, then retailers will have 9 SKU's on the shelves with most of them the old model. Logistically that's not a good situation to be in.
I think this will change. The number of SKU's for the current Switch will be brought back to 2 or 3 at the most for logistical reasons.
With Switch2 being rumored to debut at $400, they have to keep providing an entry level model. I cannot imagine parents buying multiple $400 consoles for their 8 year old kids.
I could imagine a Switch mini/pocket being introduced to replace the current SKU's. Think Switch without dock for $200. and sell dock separately. After Super Famicom was introduced Famicom stayed on the shelves for years at half the price of the newer model.
If such a new budget Switch SKU would be introduced, I can see it adding another 15-20 million lifetime sales and Switch would surpass PS2.
