If the PS3 and 360 have a similar number of releases, could it be that all the physical releases were just more evenly divided across all the platforms then? I'd be curious what the total number of physical releases were for each generation. PS1 and PS2 did get huge amounts (though this was when digital releases weren't even an option), but they also really dominated their generations. In comparison to the PS1's 4104, the N64 got fewer than 400 worldwide. The PS3 didn't have the same kind of stranglehold on the industry that its predecessors had.
