I took a chance with my breath and didn't take any Clorets:

I don't have an official page for ASRock or Gigabyte (but I've read they do sorta), but with the big 2 (imo) on the bandwagon, it's a pretty good indication that your shiny AM3 mobo won't be completely useless in 6 months.

It doesn't get much more shiny and fantastic than this.

AMD doesn't "officially support" anything of this nature. I don't know why AMD would want to keep this a secret, unless they exist to spew FUD (or anti-FUD?) any chance they can.

I bought my motherboard with the knowledge that it may ro may not have AM3+ support, but the page has been updated since then, and it's on "the list" so I may yet be "happy" in the summer.

wooo!!

Yes but does it have an AM3+ socket with the extra pin?

From what I read they just mean the "Chipsets" are capable of supporting AM3+ but not the sockets themselves due to this "extra pin".

There's an extra pin on the socket, there isn't necessarily an extra pin on the processor. That's the sticky point now raging on certain online pissing contests, er forums.
