Cherry MX switches shortage?

Is it true that these switches are still in short supply? Went to a store today (It's this one BTW), asked a staff and he said that manufacturers, such as CM, are still in short supply of their mechanical keyboards due to insuffucient supply of the Cherry MX switches. I thought it wouldn't take that long. considering that these switches had been around for a while.

Specifically I wanted to try out the Brown switches, but there's none in NZ AFAIK.

i just baught a Corsair K90 and it has red switches, so i have no clue if thats a sign that there isn't a shortage of  them. idk Great keyboard tho, recomend to all!!
