well it looks like some FG players in Japan picked up PS4s.
On the other hand RIP BB sales, doing about as well as GG now on home console.
The game, like XrdR, did the demo push on digital preorders, so who knows. I don't think mediacreates includes those.
But you're right, it's probably lower. BBCP had an opening of over 70k on PS3. Combining PS3 and PS4 and however many digital sales the game got, I doubt it reached those same numbers.
