I'd be willing to bet that there will be a 3rd jersey re-introduced within 3 years.
Kinda sounds like why they're cutting the 3rd jersey to make production easier.
It'll be a lot easier to roll out two jerseys/special jerseys (Winter Classic/Stadium Series) in 2017-18 then introduce 3rd jerseys a couple years down the line.
So they'll make money with people buying the ADADIAS version of the original jersey (or slightly altered original/3rd jerseys becoming home jerseys for some teams) then when everyone has one of those, they'll introduce the 3rd jersey again and make more money off that.
Also, if I read another article from an American writer/news source that calls the hockey sweater a "kit," I'm going to track him down and whiz on his shoes. It's hockey, not soccer you pompous jackaloon.
