it doesnt have to be as powerful as a ps or xbox but it should be strong enough to get a good 3rd party support. The Switch would not be a worse console if it would have Battlefield, The division and a cod . I mean some rounds battlefield on a couch with a handhelp switch would be a reason to buy it for me.
Switch is powerful enough to get third party support, it's just up to publishers whether they want to provide that support. The Switch could run COD, Activision just can't be bothered.
