They developed the architecture for the FX processors a very long time ago, back when Phenom II was competing with the pre-Sandy Bridge Intel designs. The first iteration never saw the light of day because it wasn't able to out-perform Phenom II in any respect, or clock high enough to make up for it. The "Bulldozer" FX processors were actually the second revision of the architecture, and Piledriver the third. It was designed all along to work in AM3, but if AM3 hadn't been able to support it properly, AMD could and would have designed a new socket for it, just like they did for the first two generations of APU's.
Socket architecture doesn't mean much, anyway. Intel churned out dreadful factory overclocked Pentium 4's and outstanding Core 2 Duo's on the same Socket 775. Back in the day, Socket 7 could run sluggish classic Pentiums that weren't much faster than a 486, or 550 MHz K6-III's that could give early Athlons a run for their money. As long as there's enough infrastructure to max out the data i/o section and enough pins to deliver power, a socket is fine for that CPU.
