Current Switch sales figures show the concept is great of a hybrid console but technically with it's 20nm fabrication process and slightly bulky size for a portable it can be much improved on. I can only see a revised Switch doing much better especially if at a better price and a large established software library.
Apart from shrinking the console to make it more portable or/and much better battery runtime there are other options as well for example a Switch that offers current docked performance in portable mode with a 1080p screen. This could also be the model that introduces a VR visor that the console slips into.
Unlike ps4 and xbox the Switch performance level is not so negative when each revision of the Switch adds improved portability for example.
I expect to see a minor revision or even major revision early next year. The minor may be the same Switch case as original and improved fabrication process for the chipset and longer battery runtime or they may go for a more major revision. The built in storage may be upgraded, 64GB seems likely at some point. Already 32GB has become quite a major issue and possibly the biggest issue for the console so far. I'd be quite happy with a double microSD slot to be honest as an alternative to give more flexibility with storage as well as usb hard drive support when docked.
It's always hard to predict sales but I personally think the later versions of Switch will be a better product for most people and you would expect that to have higher sales. Ultimately it's Nintendo's own games which I feel are the real driving force though.
