O'reilly no longer selling ebooks

So, O’reilly are no longer selling ebooks directly:

As someone who spent most of my book budget each month on O’reilly drm free ebooks this is upsetting news.

If publishers like O’reilly feel the need to do what do we think it means for the future of DRM? Is it likely that in 10 years if I want to read a DRM free book my only choice will be to buy paper?
