What you're seeing is publishers refusing to accept the fact that they little value to add in a digital paradigm... or at least have a much smaller role to play. So, they're scrambling to say "I matter!"
the days of when you needed a publisher to print thousands of books, and do a marketing campaign are over.
In the future, their role will be to front authors money for books, act as an editor, set up author tours, maybe do a little on-line marketing, and handle the technical ins/outs of e-book sales (for authors who aren't so savvy). That's a much smaller organization.
When the system matures, there will be entities who can do all those things, and the tools available for authors to do it themselves will be much better & easier to use. The traditional "publisher" will no longer resemble what it is today.
