By the way, not to rush you, but how soon can you have the core rules available? I've purchased the supplements, but the core rulebook is still only really available via torrents. I'd still like to purchase the core rules as soon as possible.
Creation of the PDF from scratch is a big task. It's not hard to create the PDF as such -- I have a Core PDF with just the pages scanned, comes in at around 150 Mb or about ten times the size of a proper PDF where the text is text rather than images. I am in the process of OCRing but that takes time -- and it is a dull task when the Core layout contains some fairly ordinary fonts and crappy layout with text over background images. So I have asked around amongst the old timers whether anyone has a copy of the original PDF that Jake made available with the original print run of Core. That was before my time so I don't have a copy myself. If I get lucky then the PDF will be available very soon. Otherwise it has to wait until I've completed the OCRing task. That'll be a month or more away.
Edit: Potentially though I could create and release the Core PDF by Book, and then when I have all 8 books done I'll re-work the PDFs into a single download. Perhaps that would help?
