Star Wars Battlefront seems to have had a great Christmas, online numbers on both PS4 and XB1 are higher than during launch week (November 21st to be exact)
November 21st:
Xbox One: 85,608 (24h peak: 110,817)
PS4: 178,374 (24h peak: 187,286)
November 25th:
Xbox One: 50,573 (24h peak: 110,817)
PlayStation 4: 98,254 (24h peak: 187,286)
As I'm posting this (December 25th):
Xbox One: 146,994 (24h peak: 146,994)
PS4: 203,551 (24h peak: 203,551)
Using current online numbers Xbox One's player count has almost tripled compared to exactly one month ago (190.66% increase to be exact), while PS4's player count has more than doubled (107.17% increase to be exact). And it's still early in the US so today's numbers should only increase in the coming hours.
