AC/DC Rock Band DLC On the Way?

AC/DC fans left underwhelmed by developer Harmonix's choice of "Let There be Rock" for Rock Band 2's setlist may have other options soon enough. Originally posted on Darkest of the Hillside Thickets singer Toren Atkinson's blog, one screenshot was intended to showcase the in-game presence of the costumed, H.P. Lovecraft-themed band's recently released "Shhh....". What caught the attention of eagle-eyed Rock Band addicts, however, was the song immediately below that one: "Shoot to Thrill" from AC/DC's legendary 1991 show at Castle Donington.
