Why does the Playstation 3 continue to receive poor ports?

[Skeeuk]

i gues they feel its the cheapest way for them, imo they should lead on ps3 with 360 in mind and make an identical port to 360. every1 is happy then.

casual purchasers will still buy a shoddy port end of day, i predict bayanetta 2 sell relatively good on ps3, but enthusiasts will steer clear
