This week's update will be the last for the PlayStation Digital Comics store, bringing to an Sony's nearly two-year-old service for the PlayStation Portable.

Announced in August 2009 and launched four months later, PlayStation Digital Comics permitted users to download comics from such publishers as DC, Marvel, IDW Publishing, Archie, Tokyopop and BOOM! Studios to handheld game console. The service amassed a library of more than 4,000 titles, which Sony says will remain available to PSP users.

In a brief announcement made Wednesday on the PlayStation blog, Grace Chen, director of the PlayStation Store, wrote that, "The Digital Comics Team will continue to work on bringing the comic service to other Sony devices." That suggests the service, or one similar to it, may be available for the PlayStation Vita, expected to be released in early 2012.
