I just wish they'd stop with all the screens in console milarky. They should have two versions of the console. One with a screen for £280, and another just for under the telly for say £200. I don't need the screen, the rare times I might possibly need that screen are few and far between, I just want to play Zelda on the telly.
It's just like kinect for me, some might like it, but there's a large group that'll never need or use it.
I've never thought about this until now but i'd imagine theres a very high chance of this happening in the future. Especially since Nintendo is fond of bringing out additional versions of their consoles each generation
We will probably end up with the 'home console' version above for around the price you've stated, the current Switch and an updated version which may have a bigger screen, better battery life and specs etc etc similar to how we have the 2DS,3DS XL and the new 3DS. This is assuming the Switch doesn't bomb but i doubt thats going to happen as Nintendo has enough fans to keep it afloat.
Worst case scenario they can simply lower prices on the console. The Switch hardware isn't anything like the PS3 where Sony was estimated to be losing $300 per console on release. Nintendo has enough pennies in the bank and they're probably drawing even on the console cost so they have plenty of freedom with how they price the hardware.
