Hate to say this, but the rock and train has well and truely left the station on this idea. ACDC's new album has been out for ages. By the time a ACDC pin could be developed the energy and excitement for their lastest album will have died. Will they make another album...... maybe, but maybe not.

The new Pin needed to debut at the same time as Black Ice's release, and be out there for when the guys are touring. An ACDC album release is the music industry equivalent of a Harry Potter movie release. I cant think of a better pinball theme! I would sell all my machines just to own a new ACDC pin.
The timing would just suck now, its opportunity missed.
