Of course that are the relics.
Back when Realm Reborn was within it's closed beta and they launched their first job video where we all could see our beloved Paladin, Whitemage, Monk, Bard and Co. for the first time, they all had equiped their relics. And if I remember correctly the Ninja aswell was shown in videos very early with his relic. For me, there's no space to doubt these are the new relics. In class Videos, SE usually uses the propper relics.
