News About AC/DC?

On the AC/DC forum I moderate, someone posted that there is going to be a major announcement concerning AC/DC on Friday. This person is pretty reliable and claims to already know the news. I'll find out Friday what the news is, if any.

AC/DC last release was 'Stiff Upper Lip' in 2000, and the band has not played a show together since late 2003. I know all of the die hard fans have had their patience tested either waiting for new material and tour, or waiting on the band's retirement. I hope it is the former.
