Pokemon Go has added 2D sprites of Latias and Latios to the game's servers, hinting that they will be the next Legendary Pokemon to be added. While Pokemon Go usually adds 3D sprites, the game is using 8-bit graphics as an extended April Fool's Day prank. The two Pokemon are known as the "Eon duo." Latios and Latias are believed to be announced as Lugia's replacement in raids, since Lugia is set to leave Pokemon Go on Monday.
