According to the latest information shared by YouTube channel The Phawx, GPD will soon launch the Win Mini gaming handheld. It is not a successor to the Win 4, but was developed as a replacement for the Win 2.

Sources say the GPD Win Mini gaming handheld has a flip-top design and measures 167 x 108 x 25 mm when closed. This handheld is 5 mm wider and 9 mm taller than the Win 2.
The Phawx video that the handheld is equipped with a 45Wh capacity battery, 12% larger than the Steam Deck. In addition, the GPD Win Mini will include a display of about 7 inches, with a resolution of 1080p and a ratio of 16:9.

The GPD Win Mini will also come with a full joystick design, front-facing H1 and H2 programmable buttons and an improved ergonomic baseplate grip. Sources say GPD will launch the Win Mini on Indiegogo in July, with delivery scheduled by October 2023.
