I honestly think the most interesting story in the next 5-10 years for Pokemon will be how the 2020 boom and the significant increase in squirreling away sealed product for future stonks affects the long-term prices of sealed product and cards from the SM era onwards. It’s not exactly unprecedented, but I will be very interested to see where an Evolving Skies box is in 5 years.
Modern is so incredibly hot right now that it’s hard to bet against it. But it also has all the elements of an unbalanced market with a ticking time-bomb of artificial demand–people don’t actually want to buy the product, they just want the money they believe the product will be worth in x years. Of course this doesn’t matter too much if there are enough people still coming in organically.
If anything was ever a 5/5 risk factor, modern sealed at above MSRP is it.
