DC's new Batman Beyond title, which premiered yesterday, will continue to be released on the same day digitally, at the same price of $2.99.
It will be interesting to see how this plays out. You'd think offering the digital comics at a lower price might provide readers with incentive to migrate to screen, vs. paper comics. But I suppose if publishers can pull off this trick without reducing revenue, they'll go for it. Ultimately, if paper comics go away, or largely go away, the publishers stand to make greater profits, since they won't have to contend with costs of printing, distribution, etc.
Personally, I have a hard time seeing myself making the transition as a reader. I like tangible books, comics, albums, etc. But I find myself downloading more and more music these days rather than buying CDs.
