Big question is if it would use X86 or ARM. Steamdeck uses X86, Switch uses ARM.
ARM is usually better for battery live and might overall be a cheaper design. But if the PSP3 would take advantage of ARM there would not be a plug-and-play for the PS4 library of games. These games need work in porting them.
If it uses X86 it has the same challenges as Steamdeck in battery live and price. Or in other words a portable PC, not a dedicated handheld/hybrid design like Switch.
Other question is if such a PSP3 would support physical media or be digital games only. If digital only it would limit its appeal.
