The Devil May Cry HD Collection has been rumored since this past June when a Spanish retailer posted an ad. Since then no new details have been released, until today. Capcom hasn't confirmed anything but the ESRB has publicly re-categorized Devil May Cry, Devil May Cry 2 and Devil May Cry 3: Dante's Awakening. "Change Value of Platforms from "PlayStation 2" to "PlayStation 2, PlayStation 3, Xbox 360." Meaning, these games are no longer just for the PS2.
When the rumor of a Devil May Cry HD Collection first started it was widely believed it would be a PS3 exclusive. If these changes prove to be true, it will be released on both the PS3 and Xbox 360.
