As recently as Monday, DC wasn't publicly committing to anything when it came to digital comics. As of this morning, DC Comics are available via iTunes. Including the release of Superman #700, which is released today.
In no way does this appear to be an original strategy, but at least they didn't wait much longer to unveil part of the plan.
I have to wonder if plans were to roll out the digital initiative at some other point (San Diego?), but reports that began surfacing this week about Marvel's relative success, and possibly even the story about Hastings getting into the comics game didn't drive the decision to flip the switch.
Well, iPad users, your time is now.
Update: DC's official press release.
Update Update: I was a bit curious as to why DC teamed with Playstation rather than X-Box when it came to their upcoming DCU Online system, which is PC specific for computer and PS3 specific for consoles. But I am guessing that the Playstation Comics thing was already planned, or part of that strategy.
