I’m excited for new first party GameCube controllers. I still prefer them, especially for Smash, and the PowerA versions only last 3-6 months before a button or stick starts getting wonky.
The GameCube controller is still my favorite controller of all time! I use the originals on my switch with an adapter, but the fact that it only has 3 shoulder buttons and buttons can't be remaped make it not suitable for all switch games. I'm hoping this first party controller will improve that situation, but we'll have to see. It appears to still only have 3 shoulder buttons, but hopefully they will let you remap buttons - they have been oddly selective about what controllers they support remapping for on the original switch.
