I'm so confused by this thing it's not even funny. EA has announced the Battlefield 4: Showdown Live Europe vs. USA event that will pit two teams of 32 against each other.

The Showdown will be live streamed through Xbox Live and will "mark the debut of Battlefield 4 Second Assault," which is an expansion for the game that includes four "fan-favorite" maps from Battlefield 3.

Yes, the Xbox One will get this expansion first.
The event will be live streamed on Xbox Live online entertainment network from Microsoft on November 1 at 10:00AM PDT. The Showdown will mark the debut of Battlefield 4 Second Assault, an expansion pack available at launch first on Xbox One, the all-in-one games and entertainment system from Microsoft. Battlefield 4 Second Assault includes four fan-favorite Battlefield 3™ maps re-imagined with the power of Frostbite™ 3. Top-tier Battlefield players will be hand selected to represent their country as they battle it out on Xbox One.

Xbox Live’s Major Nelson and AceyBongos will command their respective squads to lead their teams to victory. Starting today and ending on Sunday, October 6, Xbox is offering one lucky gamer in the USA the chance to be on Major Nelson’s side by entering the Battlefield 4 “Play and Win” sweepstakes*. Players can download the Battlefield 4 Gamer Pic and play the Battlefield 4 beta** on Xbox Live this weekend for a chance to win a trip for two to London, two passes to the event, a seat on the USA team and a $500 gift card.

So, this tournament will take place on the Xbox One and that platform will get the first go at the Second Assault expansion. Well, that's something.
