Not only that but a lot of people are opting for smaller form factor PC's that fit a more casual entertainment lifestyle rather than big full size enthusiast atx towers and with AMD at this current moment you are pretty much forced to go the FM2+ socket (due to AM3+ CPU's not having integrated north/southbridges and therefore requiring bigger motherboards) for such builds which isn't optimal for anything above low end gaming.
Being able to slap an octacore chip into an itx motherboard would be a nice incentive to go AMD.
if you're willing to pay for it you can already get a mini-ITX motherboard which can support upto a 18 core Xeon CPU - the Asrock X99E-ITX/AC, however it's crazy expensive $260/£270 (Amazon UK / Newegg US)
a 8 core mini-ITX at £/$ 150 to 200 would be quite cool though
