Can`t be about the Vita as Sony made some comments some time ago about Vita getting less big games as it made less sense business wise, if i`m not mistaken.
The more expensive reference has got to be about PS4 games. Vita games can`t cost a whole lot more than PS3 games to be the target of that comment. It makes more sense if he`s speaking about PS4, seeing as, again, costs have gone up and they require more manpower than ever.
Didn`t Ubisoft said something along those lines, like, they would invest less on new franchises?! It was something like that.
One thing`s for sure, don`t expect a lot of new IPs if the new ones can`t pay for their development in a meaningful way.
