With the new Night Birch we are at 4 in under 2 years. Have to assume a Tiffany Blue model is next, cause, why not? Now that titanium is in the mix, probably should expect a Spring Drive Night Birch as well.
I’m going with 8 variations by 2024. Any takers? @HotWatchChick69, this may be a good opportunity to wager against @Deeperblue so you can change your name to something less provocative. Or more. I don’t shame the game.
