When the dust settles fellas, no need to panic - why? For the following reasons:
1) Many collectors spent a pinch on mojos since 2015 in particular paying as much as $800 for a sapphire set last year and even just as much for ruby in 2015 when that was the sole variant at time and this simply means those in those such PCs will never come out unless someone was prepared to pay as much as they paid so therefore holding SOME value
2) Yes bad news is quite possibly Emerald mojos could possibly plummit to $400 this Christmas period but that mainly being for Titans, Warriors and Knights 10/10 sets however would not be surprised if some crazy collector will pay $1600 for a Thurston 07/10 Emerald set or same for Bunnies, Eels or Saints 01/10 and once they bought they're gone under the pillow and not to be seen angain lol
3) Some collectors will simply not consider emerald mojos as a part of their collecting goals due to their small abundance so even if there is a purple-diamond variant next year same procedure would apply
4) Yes bad news is should ESP go even further with Purple-Diamond /05 mojos next year and finally Black-Diamond 1/1 variant at the same time and then on, that could arguably mean Ruby variants could auction off as little as $40 not to mention Sapphires @$65 plus Emerals @100 but the good news is, considering ESP have contracted the license to end of season 2022, that would mean collectors would technically receive five opportunities to obtain a 1/1 Black mojo set not to mention 25 for purple variant lol should they become an ongoing tradition in series 2 releases
Anyway, that's my thoughts in such regard
