PSP Digital Comics store will launch in several countries today. According to a PSNComics tweet, the US will receive access at noon Pacific time (3PM EST). The European PlayStation Blog states the comics store will open at 5PM GMT in the UK,
The system will supposedly launch with hundreds of comics from Marvel, IDW, Titan, iVerse and 2000AD. Everything that's available should be listed on playstationcomics.com after launch. We're definitely looking forward to taking the service for a test drive with that "free comics" button.
