They have started to garner attention from the WWE Universe lately, something that was previously missing during their singles run. Therefore, Triple H might keep them in the tag division for a few months.However, Fenix and El Idolo could eventually part ways and head on their individual paths. It is because WWE may not have any long-term plans to push them as a team. While a split may not happen right after SummerSlam, it could happen in late 2025.Andrade is one of the top talents on the current roster who has gained prominence for his singles run in the past. Therefore, the creative team may push him as a singles star on SmackDown. Meanwhile, Rey Fenix has already made a career as a tag team competitor in AEW.The fact that WWE used him as a singles star in his initial days in the company indicates that the creative team may eventually push him in the singles division. However, it is all speculation at this point, and only time will tell what happens.
