How could you want a PS3 for 1st Party games? I mean unless you are a hardcore Gran Tourismo fan most of their 1st party games are nothing to make you go out and buy a console. They have some nice second party stuff... Even if you combine those it is really weak. What make the PS3 worth the purchase is exclusive 3rd party games (FF, MGS, etc.)
