The FCC has published documentation concerning a new version of the Nintendo Switch, including photos of the changes that Nintendo has made. However, this is not the upgraded Switch Pro on which Bloomberg reported earlier this week. Instead, it seems that Nintendo will be releasing another revised version of the Nintendo Switch, just as did last year. According to a Class II permissive change letter filed with the FCC, Nintendo has changed the SoC, memory and CPU board.
The new model is called HAT002, and the FCC has published some photos of the SoC, memory and board changes. The photos are low-resolution, but we can make out "NVIDIA 1923A1". While we cannot find out much information about this chipset, a member of ResetEra forums has determined that it resembles the Tegra X1+ that Nintendo shipped in last year's revised Switch.
The FCC documentation also refers to the HAT002 supporting Bluetooth Low Energy (BLE). However, the existing Switch uses Bluetooth to talk with wireless controllers, so we doubt that Nintendo is expanding the Switch's Bluetooth capabilities. There are no external changes to the design of the Switch, either. The FCC has published test photos that confirms this, which we have linked below.
Nintendo announced the last revision via a tweet on its Japanese Twitter account, which was then picked up by various outlets. Hence, we would not be surprised if the company does not make much noise about the release of this new revision, either.
