I've always felt the first-person view to be quite an afterthought, it has always been fairly glitchy and the game not really benefiting from that close view. Perhaps in a future release where such feature is meant to be included from the start, it would feel logical to take more attention to all those smaller details otherwise not noticed from the isometric point of view, but in regard to TS4, it would seem to me like a massive waste of resources.
I perceive the first-person camera more as a means to take nicer screenshots from the Sims' point of view, not as much as an integral part of the game.
