I think the only real difference to be honest is if Switch is super successful then Sony/Microsoft maybe even Samsung or Apple will release similar products. Which might be a scenario that isn't so desirable for Nintendo anyway.
Having a solid success but nothing mind blowing might actually be better in the long run actually.
Developers are going to focus on PS4-XB1-PC for the next 3-4 years regardless of what happens so not much changes there.
Nintendo makes a lot of money these days even from just the aging 3DS + dead Wii U + mobile they made a ton of money last quarter, so as long as Switch is not losing them money, they should be fine for the next five years.
