That's a common request but there are no plans to officially offer PDFs. We offer a variety of reflowable file formats, and each format is more burden to maintain; since PDF is a famously difficult format, maintaining it would be even more burden. A reader requiring a PDF can use a tool to convert any of our files to PDF. That's basically what we'd do at the end of the day, anyway. There's been some mailing list chatter lately on how to best format PDF editions, but that's not being pursued on a project level.
