Can't see this happening. Sales will most likely drop after PS5/Xbox release. At that point Switch won't be up to date anymore so that Nintendo will need to release a new console.
No wonder the Vita failed. It was not up to date with the 3DS anymore...... oh wait!
Nintendo will have more planns with the Switch. Like look at Labo. That thing will release just after 1 year of Switch.
Pocky Lover Boy!
