The next Nintendo Switch revision, which has been rumored to be in the works for a while, will feature an upgraded OLED screen and may require a new dock, according to new information shared online.

SciresM, a well-known console hacker and dataminer, discovered a new Nintendo Switch revision codenamed Aula, as reported on the ResetERA forums. This new hardware revision will apparently be using a Mariko SoC. This new model won't be a docked only one, as Aula does support handheld mode.
