Led Zep with Steve Ritchie could be EPIC ! Hopefully with a great artist/hand drawn art...the Zep art could be lurid and fantasy-based, as are many of their songs. Tonnes of art material there.
As others have said, I would love this to be a full blown cornerstone release by Stern and not a reskin. If it's Ritchie...hey Steve!! How about a non-fan-layout? Maybe a third (or fourth) flipper!!
...and hopefully they license the truly rocking songs: Black Dog; Communication Breakdown; Immigrant Song; Rock and Roll...etc...
