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."
The Pro 2 was notable for having an easily replaceable battery pack which was also compatible with standard AA batteries, and now the Pro 3 will be removing this feature in favor of an internal battery. I was implying that although the Pro 3 includes a new hall effect sensor for the triggers which would marginally increase its lifespan, the Pro 3 will likely need to be thrown away sooner than a Pro 2 because of its new irreplaceable battery design.
I was thinking about my Ultimate 2 anyway, so my comment didn’t matter. Maybe I’ll get a Pro one, some day.
You should still be able to disassemble it and solder on a new battery if you have the tools, the time and the knowledge
