Day one? you are not serious ? do not you know that developers get dev kit so early ? Secondally as I said i was reffering to Programming language which takes time to code on new architecture . It true that there will be room for improvment, for example you can write your code in better way than i did, although at the end of the day both codes will do the same thing , I also believe first games for any system are somehow rushed that is why i think Guerrilla studio did not call it Killzone 4. Also as Bit_reaper said the difference will be so small compare to current gen.
