A Nintendo Switch Pro has been reported to be in development by the Wall Street Journal for 2019. It is expected to result in a dual marketplace of either regular Switch and Switch Pro or a Switch Lite and Switch Pro being sold in retail stores. The non-Pro would be the "budget" variant.

TOKYO—Nintendo Co. plans to release a new version of its Switch videogame console next year to maintain the sales momentum of the device, according to suppliers and others with direct knowledge of the plan.

Sales of the Switch, introduced in March 2017, are still solid but are no longer delivering the favorable surprises that marked the machine’s first year on the market. Nintendo shares, which rose sharply last year, have trailed the broader stock market this year (2018).
So is this a good thing, a bad thing, or just the usual Nintendo thing? Personally, I'd be in favor for a price drop for the regular Switch or a sub-$300 Switch Lite!
