As pointless as it could be. For one, because it doesn't cover the Pro controller, which also drifts - but more importantly, because simply getting a replacement doesn't mean it won't break again, it will. This seems like an easy thing to fix at a manufacturing level, they should just make new Joy-Con models.
This is just a short term solution. They have to do something now than just make promises for the future. Who knows if they will set a deadline for this, but it seemed like it is confirmed for NA while other regions are still uncomfirmed.
Pocky Lover Boy!
