>>21337983X/Y didn't have demos beforehand that were datamined. Plus, we discovered a new mega in the demo files that goes unused, which implies there may be no more new ones.
HOWEVER, the demo is partially scrubbed, as it doesn't include all of the music in the game and there's massive gaps in the item index, implying that they may have scrubbed data or that the demo uses an incomplete build of the game.
