I am not sure that the PI4 is the burner. There is no handheld gaming console for the PI4 and the PI3B+ with some overclocking is not far from the power of the PI4. Because the CPU speed alone is not just a criterium, there are other parameters. So, if you would use it, let's say, in a bartop or some other case, better to move for a PC Itx board. Muuuch more power and connection possibilities. Raspberry was too slow in development the last years and concurrence is not sleeping. I personally see no interest in such release. 35 $ or Euro is for sure cheap, but will not bring much further in gaming power.
