Here's the "Switch Pro" you've been waiting for. It's like the rumor suggested, a modest upgrade and not a Pro at all.
Looks exactly like the original Switch and the only noteworthy improvement, according to Nintendo's website, is the battery life (see image below). The original Switch SKU can be expected to be phased out in favor of this look-alike. Price and internal storage (32 GB) will remain the same for the updated SKU.
Supposedly, the HAC-001(-01) model will be made available at different points in time in different regions, probably in accordance to current stock levels. The Americas will get it in mid-August, Japan in late August, Europe and the rest of the world in early September. Check the official Nintendo website of your country for information on the vague launch date.
