ArkhamCity.co.uk, who have been ever-vigilant of Arkham City details, captured the information before the web pages were taken down.
A "Nightwing character pack" was dated November 1, for $6.99. The site also listed a "Robin bundle" will hit on November 22 for $6.99, with a nondescript "Skins pack" to swoop in on December 6 for $4.99.
With the convoluted way Arkham City character skins are being distributed among retailers, it's only a matter of time before all that fashion is consolidated and sold to the ravenous masses.
Update: PR confirms some of the details after the break.
