Yes, one of the bonuses listed with the Hero Edition -- alongside an 8.5" Cole MacGrath statue, a voucher that gives access to new powers, weapons and character skins, an inFamous comic from DC Comics, and the game's soundtrack -- is a "Replica Cole MacGrath sling pack." We must have one, if only so that we can be halfway to becoming a city-climbing crimebuster. (All we'd need is, you know, powers. And courage. Like, any courage at all would help.)
The special edition also includes a $99.99 price tag, and a super unofficial May 24 release date. We've contacted Sony for more details about ... well, everything.
