It appears the anticipated sequel to Battlefield 4 will not be Battlefield 5. Instead, EA has apparently thrown traditional counting out the window by preparing Battlefield 1, a new shooter that seems to be set in an alternate history version of World War I.

None of this is official yet; EA is set to actually reveal the next Battlefield title as part of a day-long livestream at 4pm Eastern time today. But the name has been leaked ahead of time by photos from a retail source. The promotional art in those photos matches art that showed up briefly on Xbox Live earlier today and on the livestream itself, depicting a figure with a WWI-era pistol and trench club. There have been previous rumors about the game's setting, too. Back in February, a game called Battlefield 5 was briefly listed as a "WW1 tactical shooter" by a Swiss retailer with an October 26 release date.

Remember that the first Battlefield game (the one people sometimes call "Battlefield One," and which came before Battlefield 2) was actually titled Battlefield 1942. The name Battlefield 1 remains technically available, we suppose. The series has already jumped around to "1943" and "2143" over the years if you want to get really confusing with the numbering.

Really, 1 following 4 shouldn't even make us blink in a gaming world that includes Resident Evil Zero, Kingdom Hearts 358/2 Days, Madden NFL 25 (which followed Madden NFL 13) and, of course, the Xbox One console.

[Update: Another shot of the leaked retail materials tweeted by industry sleuth Wario64 suggests an October 18 release date for the game.]

[Further Update: Yup, the game is actually called Battlefield 1, and features all sorts of World War I trappings, like Red Baron-style biplanes, saber-wielding troops on desert horseback, mortars, and plenty of zeppelins. Release date is October 21.
