I never saw the point in getting the PS4.
Graphics don't look that much better then they do on the PS3, you have to pay to go online gaming with the 4 and they both do the same things from what I can tell, plus the second hand games market is huge with the PS3 so you'll always be able to get cheap games.
Good spot with the Zed btw.
Graphics are always roughly the same at the start of a new generation consoles life, they get better as developers find their feet with the various software tools available. The games at the end of the Xbox 360 and PS3 were much much better than when those particular consoles first came out.
