This is how I would do it.
Switch Lite (launches Spring/Summer 2019)
Die-shrink Tegra X1 chip to 14nm FinFet
Left/right bezels on Switch eliminated, resulting in smaller system (less width)
Less weight
60% increase in battery life
Price reduction to $249.99 for holiday 2019 with Mario Kart 8 Deluxe or Breath of the Wild bundled (user's choice)
Switch Pro (March 2020)
7nm custom Nvidia Tegra (comparable to Apple A12X)
450-500 GFLOP undocked, 1.2 TFLOP docked
8GB RAM with 58GB/sec bandwidth
1080p 7.4 inch display, 128GB onboard flash storage
$349.99 MSRP
All Nintendo games run on both models, only difference if you have a Pro is the resolution will increase to 900p-1080p undocked and 1080p-1440p (4KTV required) docked. Same with the bulk of indie games.
Nintendo does allow for about 10-12 3rd party games per year that are Switch Pro only. Kingdom Hearts 3, Resident Evil 2 Remake, Call of Duty, GTAV, Dark Souls III, Fallout 76 in 2020. Goal is not to get every 3rd party PS4/XB1 title, just a few of the bigger ticket ones. Eventually this number will rise and Switch will transition over to Switch Pro as main model and Nintendo will start making some of their own games Switch Pro only (around holiday 2021).
