It wouldn't be surprising if the RP2350 gets officially certified to run at something above the max supported clock at launch (150MHz), though obviously nothing close to 800MHz. That happened to the RP2040[1], which at launch nominally supported 133MHz but now it's up to 200MHz (the SDK still defaults to 125MHz for compatibility, but getting 200MHz is as simple as toggling a config flag[2]).
