Nintendo Switch Pro has been rumored for a long time, but nintendo itself is very secretive, and no official details have been disclosed. However, according to @PixelPar, a whistleblower who previously leaked Splatoon 3 themed Switch OLED models, the Switch Pro could launch in September.
Although the timing is not official, given the Revelations, it is plausible.
As previously revealed, the Switch Pro will feature an Nvidia Tegra chipset with more memory, and will be able to connect to a larger screen via the TV dock, supporting 4K output.
In addition, he said that the new phone will be compatible with the existing base, the design will not change much, and the screen size may be a bit larger.
