This is a tone-deaf company who are blaming their loyal fans that environmental interference is causing the Joy-con and Wi-fi issues. I don't think the Joy-con issue will be fixed. It's a hardware issue. The right thing to do, is to redesign the left Joy-con and issue a recall. Nintendo will not do that.
As some gaming journalists pointed out, it's clear that Nintendo designed the Switch with a second iteration in mind. Happened with the GBA, DS and 3DS...and will happen again.
