Correct. The only special equipment was Gentian's event's Pumpkin equips and the current ones. The Pumpkin equips are great for counter girls and for non-counter are competitive with high-grade equipment (I want to say +8 or 9ish?) but it's not a huge loss.
Of course, since that was the first event with special equipment, it could very well mean that the equipment will be obtainable in its eventual reissue as well, seeing as all other events have merely had ampies, manyus, coins, seeds (gacha and equip) and sometimes evolution dragons as extras (with the gacha event having 3*s) all of which are farmable anyways. The fact reissue events have you collect event currency and turn-in at shop is conducive to including the event-specific pumpkin equipment when the time comes (just another option added to the event shop)
