I am aiming for October. It will take me about 4 weeks to do lay-in, cover art, interior cover, etc. Obviously it can't go to press without a finalized list of names for the Acknowledgments, so the first round goes to the printer for proofing as soon as the 45-day fund drive is up.
After that, I will receive a hard proof copy from the printer (I'm estimating this will take 4-6 weeks), check that for errors and any necessary revisions (probably a week or two), then send the final files to press.
Shortly afterwards, folks who have pledged for the PDF copy will receive an email with a download link.
The physical books will take a while to arrive in Austin and ship out - packaging, post office runs, doing the sketches and everything - but that process should not begin any later than early October.
Depending on how fast the printer operates, this *may* all go faster than anticipated, but I'm being conservative in planning here and allowing for glitches :-)
