That's literally a pitch altered version of the original Celine Dion/Peabo Bryson version. No way that they would let a high profile track like that leak so early.
Also, I'm 95% positive that this new recording of Emma singing with a full orchestra is just the trailer audio layered on top of the orchestrations from the musical. It's not amazing quality so it's hard to tell, but if you listen closely with headphones you can still hear the eerie piano from the trailer, and very faintly, another voice layered underneath hers toward the end.
