The peripheral prices won't hurt launch window due to the nature of early adopters. It's still a dick move that hurts overall consumer confidence and trust, things Nintendo can't afford to take lightly after Wii U flopped.
part of my reasoning for even early adopting would be to play w/ my daughter, which means I will need a 2nd set of joycons and a grip. But for $110.00
before tax, it's more than 1/3 the cost of the system to buy an complete additional controller. That's just OUTRAGEOUS and turns me away from not only early adopting, but adopting at all.
I'm not spending $410.00 + tax on this system to play multiplayer, only to realize that I haven't even picked out a game yet.
If I'm not sold at launch, then I'll just have to re-evaluate at Xmas time.
and i know lots of the 1st party multi uses split controllers, but what if the game I want to play doesn't?
oh, and come Xmas time, I really hoping Nintendo pushes that VR Headset and some exclusive MMO Star Wars Jedi Knight VR3D game w/ split joycon controls (ep VIII tie in). You want to make a frenzy as hottest thing during Xmas 2017, that would be the product right there.
edit: I'm not even a SW fan, and I would buy in for that. possibly even pay for the online service to play it too.
