Those two sockets where AMD glory days of performance over intel, no one at that time line had compatibility. Actually you can > http://www.gigabyte.com/products/product-page.aspx?pid=3581# It might not support BD or PD but it supports everything else. And those CPU's can also be used in socket AM3+ Thats a pretty wide range. You wont find that support from intel anywhere. I get what you mean but the support is there one way or another if its an old mobo with a new upgrade to CPU or then if you want to have the use of USB3 etc you can still use your CPU from your AM2 mobo and put it into an AM3+ mobo, you don't have to buy two parts every time you wish to upgrade, you know what i mean? So you mean server CPU's?? not desktop? and if that's the case why do they need a new socket then for this new 8-core desktop CPU's? Ok yes for DDR4 but that's just silly. That might be ok for you but when you have spent alot of money on a top end mobo with all the bells and whissels on it (FYI AMD has had those features for yrs now 6GB/s ports and plenty of USB3 ports) I for one wouldn't like to dish out another 200-300$ just so I can support a new CPU each or next year. $500-600 for what 8 core processor? if you think this one from intel will be that cheap you best think again.
