From the linked GameSpot article:
"8BitDo has revealed the successor to its popular Pro 2 Bluetooth Controller. Officially called the Pro 3 Bluetooth Gamepad, the upcoming controller retains the form factor of the Pro 2 while implementing some of the enhanced features found in the Ultimate 2 Bluetooth, such as TMR joysticks and trigger locks. It also has a few entirely new features not found on other 8BitDo controllers, including swappable magnetic face buttons and an extra pair of arcade-inspired ball-top stick caps.
The 8BitDo Pro 3 Bluetooth Gamepad is available to preorder now at Amazon for $70 ahead of its August 12 release. It comes in three retro-themed colors: G Classic, Gray, and a shade of purple that pays homage to the Nintendo GameCube. All three models come with matching charging docks and a set ball-top arcade stick toppers that can be swapped in for the traditional rubberized caps. Out of the box, the Pro 3 is compatible with Switch 2, Switch, PC, Android, Apple devices, and Steam Deck."
I find this annoying. I have three different 8bitdo controllers hanging around my house. I have the original 8bitdo sn30 pro, the pro plus, and the pro 2. After I bought the pro 2 they came out with the Xbox variant. The difference between the pro 2 regular and the pro 2 Xbox variant? The additional rear buttons on the Xbox variant work and are mappable in steam os. Where the ones on the original pro 2 are not. Do both of these controllers have the ultimate software? Yes. But unfortunately one of them doesn’t contain the hardware to make those physical buttons work as physically and programbaly different than the other buttons on the controller.
I can buy this. I could buy the Xbox variant pro 2. But I don’t want to have to keep buying essentially the same controller to get functionality it should have had in the first place.
