We already know that the Legion Go 2 prototype was seen at CES 2025, but I'd like to clarify some very important things. That prototype doesn't have the Ryzen Z2 Extreme, it only has the Ryzen Z2. The display is a WUXGA (1920 x 1200), not a QHD (2560 x 1600). It would be a very bad idea to sell a low resolution even if the screen is OLED. Also, something I always see them put is that the iGPU is said to be a Radeon 780m like the Z1 Extreme. Which, well... I don't think it's true that it will ever be sold. It's more logical that the Z2 Extreme has a Radeon 890m iGPU.
Also, many of the specifications that some news media always put are not 100% real because, well... they confused a lot with the specifications of the Legion Go S and its 4 versions. In the end, it will definitely have more fixed specifications like the Ryzen Z2 Extreme as a base, a QHD OLED display (2560 x 1600), and it could also have an extra thing like 3 months of Game Pass and its case like the original. Because I don't think they'll sell it with fewer things like the Legion Go S.
