@ Robo it depends on your resources and things like time frames, development kit costs and you would know more about that than me ,although it might be advantageous if you could have some cross platform gaming with the PS3 and Vita along the lines of what Kojima was talking about in playing on the PS3 and then taking it with you on the Vita then when your home continuing back on the big screen,another thing is it ports you thinking of or turning it into a franchise with separate games on different platforms.
