1st no it can 't Wii is the winner of the 7th gen no one can deny it
2nd yes the chances are a lot
3rd it is already
but as a whole PS3 has sold way more than consoles like Dreamcast,Gamecube,Xbox,Nintendo 64 and many more systems it has an established fanbase and it is being supported pretty well so it won 't be like old 3rd place consoles(if it won 't come 2nd) it will end up as the best-selling 3rd place home console of all time
