@SOC Admiral

AM2/AM2+ Compatibility with AM3 chips wasnt a sure one either on many boards.But it went a lot better because AMD made it part of they policy,so mainboard makers knew they should do whats asked of them or face user rage.If asus could do it, everyone could.And probably with a lot more supported mainboards.
But you make a good point on one of the reasons why they chose not to.Its just that i see it as a bad move.

@Kobaltrock

I`ve never inferred JF AMD talks on behalf AMD, moreover he only talks what is official AMD policy so theres no problem really.He must have been badly informed by the desktop guys (because he works in servers) and that was the reason for such a strong comment (the pixie dust bit).He rarely goes into detail and more often uses not so precise wording.As in example "it isnt supported", can mean everything really, and informs only of the fact that AMD does not take into account such possibility as its not part of their policy.

@Flank3r

I know thats old old roadmap, i was showing it to SEA as he asked if AMD ever had plans for BD around AM3 socket.It had.It changed about a year/year and a half ago.

As for the speculation bit.If Asus delivered bios for BD`s.That means ES`s are in the wild now at last.And theres at least possibility of getting screenshots of BD working on for example crosshair IV :-), so maybe its gonna be less than 120days.
