Hm, I rather see them not spending a lot of money on many new AAA games (considering that 3rd parties do it better than any platform holder), but on more AA games instead - though, tbh, these new triple-indie games (as some like to call them) are pretty much equivalent of AA game, so it's not like PS4 is missing them either.
Anyway, nice of them to realize there is some sort of problem, whether they choose to make few AAA or crapload of AA games.
