Amazon is listing a FIFA 14 release date of September 24 in North America.
The product listing in question is for an unannounced Vita version of EA's latest football game.
FIFA 13 launched in the US on September 25 last year and FIFA 12 on September 27 the year before, with European releases following a few days later.
EA officially announced FIFA 14 for Xbox 360, PS3 and PC last week, noting that "additional formats" will be revealed in the coming months.
EA is currently seeking FIFA 14 testers for playtest sessions due to be held later this month and early next.
