I personally wouldn't use the TCG as hints towards any sort of Gen 5 remakes since it tends to bring back mechanics every now and then. For example, our current chase cards are Pokémon ex and they function in a roughly the same manner as RSE-era's Pokémon ex did. ACE SPECs are in the same ballpark, the only difference is that we now have one confirmed ACE SPEC that
isn't an Item card (it's listed as Neo Upper Energy in the article) and that ACE SPECs are also effected by the Item/Tool split that occurred last year.
