Nintendo have mentioned wanting to get the Nintendo Switch from one-per-household to one-per-person with the biggest obstacle being price, compared to the 3DS.

Kimishima said: Consumers purchased Nintendo 3DS systems in numbers we expected last fiscal year. It has an ample software lineup at a price point that makes the system affordable especially for parents looking to buy for their kids . We expect that demand to continue during this fiscal year as well, so we will continue to sell the product. Given that Nintendo Switch is a home gaming system that can be taken on the go, this situation may change if it grows from being a one -per -household system to a one -per -person system. But the price of the Nintendo Switch is not something with which most parents would buy a system for every one of their children in a short period of time. Moving forward, we will work to ascertain what kinds of play people want at which price points, and as long as there is such demand, we will continue to sell the Nintendo 3DS system. I see the product coexisting with Nintendo Switch at this point in time. |
Also note, the currently announced software lineup of 2019, by no coincidence, has a lot of marquee titles that most recently appeared VERY successful in their handheld entries: Pokemon, Luigi's Mansion, Fire Emblem, Animal Crossing, etc.
Based on both Nintendo's comments AND their currently announce game lineup for 2019, it is much more likely to be a Nintendo Switch Mini or Nintendo Switch SP than any other revision in order to satisfy their traditionally handheld gamer that prefer a more compact form factor AND parents buying the system as a gift at a lower price point than is also more durable and friendly for younger owners.
There has simply been no indication of Nintendo focusing on Higher resolutions/CPU clocks/GPU clocks at this point in time.
