I will say that the Xbox One X was a pretty big jump from the original Xbox One even though the One X was a mid-cycle refresh.
It went from 1.3 TF to 6TF with a die shrink and significantly higher bandwidth and vram capacity not to mention other improvements but the main purpose was to push that 4k resolution. So it's certainly not unheard of to have a mid-cycle refresh with a huge gpu improvement, especially if it's targeting 4k. But Nintendo doing it is certainly unheard of and it is very unexpected if true.
