Everyone wrote about that update back in March, so I would guess that today's news refers to a new update. Unfortunately I can't find it in iTunes, and Nook Media has not yet gotten back to me with the details. Of course, there is a chance that Nook Media is trying to hoodwink the blogosphere into writing ad copy for a non-story, but since I recently promised to be less negative I am going to pretend that is not the case.
I plan to update this post with the change list from the update, but that waits on more information. At the moment all that I can share is that B&N is giving away:
a free DC Comics 2013 Superman Sampler, which includes excerpts from Superman: Last Son of Krypton, Superman: For Tomorrow, Superman: Earth One, and Justice League Volume 1: Origin.
The free comic is only available to customers who download the app and set up an account for the first time.
On a related note, Barnes & Noble has been making a major effort to promote Nook news as coming from Nook Media. The press releases are still coming from the same folks at B&N, but the fact that they are working to reinforce the idea of a separate Nook Media suggests that they want to actually spin off the subsidiary. Up until this point the separation between B&N and Nook Media had largely been symbolic, but that might change soon.
