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."
