I was disappointed to learn that America and Australia get more options for Joycon colours than we do. Currently, if anyone wants a pair of red or a pair of blue joycons, the only option is to buy a neon Switch (if you're lucky enough to even find one) and then buy the red/blue Joycon pair. That or get lucky and find someone who is wiling to trade one of their neon joycons to get a pair of matching colours. Whereas in America, you can just buy the red pair or the blue pair.
Nintendo always do this, they always screw over one region or another with hardware or software releases that don't come to other regions. Most common and obvious is Japan getting games that never come West, but there's been plenty of EU-exclusive or NA-exclusive stuff too. Looks to me like Nintendo hasn't changed one bit.
Unless... they turn around and also release those joycons over here too? Is it too much to ask to have a matching pair of coloured joycons (yellow is fine, but red/blue are more popular/desired colours)?
