In H7 the priority was a new back-end and interface for the online help (in the embedded browser) and generating PDFs unfortunately fell into the “we can't do everything right now” pile (low-level: because we generate the docs from XML instead of FrameMaker, we need to set up XSL-FO to get PDFs where we used to get them “for free”). Hopefully searchable help made up for it somewhat.
In the next version, the docs focus is on creating basic content to get people up to speed quickly. Once again, PDFs are lower on the priority list. But I'm still hoping to do the back-end work necessary to generate PDFs (since it's the same work I need to do to get a certain cool WYSIWYG XML editor working). Once that's done, it would be fairly trivial to generate PDFs for the H7 docs as well.

. I can't really speak with any authority on that, sorry.
