Will I regret opening a Japanese booster box?

Going to a card show and kind of wanna try and find a Storm Emeralda booster box to open. Mostly for fun bc I really like all the pokemon that have ARs in the set and also for the novelty bc I’ve never ripped japanese packs. Just curious if I buy a booster box for 100-130 am I gonna it because the prices will drop off a cliff after delta reign releases in EN?
