It seems like the teases for the next Call of Duty game may have begun. After the new map Redwood Snow was added to Call of Duty: Black Ops III on Monday, Redditors like user MrTheRevertz noticed something different about the winter-themed overlay of the launch map, and it may have something to do with the recently rumored Call of Duty: Black Ops IIII. 

After careful examination, it seems like the license plate on the red truck near the cabin on the map has changed from its original counterpart. Now the front license plate reads 0123456, while the back reads 2QR1496 which is different from the original map's license plate of 2SAM528. You can check out images of these license plates below.

What these numbers mean (no pun intended), however, is unknown. What's interesting is that if you shoot off the license plates, they revert back to their standard "2SAM528" when they hit the ground, almost certainly meaning this was an intentional change made by the Treyarch. Only tell will tell if people can decipher what this means or if fans are just on a wild-goose chase.

Treyarch has, however, been known to tease their next game in the past. Before Black Ops III was announced they updated certain maps in Black Ops II to include a QR code, which in and of itself teased cryptic videos.

This news comes the day after James Harden, a professional basketball player, was seen wearing a hat with an "IIII" symbol on it in the same style and color as the Black Ops logos.

Call of Duty: Black Ops III was originally released on November 6, 2015, and is available on PlayStation 4, Xbox One, and Windows PC. As of the time of this writing, Black Ops IIII has not been officially announced. Any rumors regarding it should obviously be taken with a grain of salt, including this one.
