Wow! So you want to postpone the eArcs significantly from when they are released now? Almost to the first quarter release as part of the bundle? In which case they really aren't eArcs (electronic Advanced Reading Copies), but just a marginally early final version?

Right now, the eArcs at Baen are understood to be early releases, with the chance of errors. I'm pretty sure Toni actually usually waits for the first round of edits from the authors, but it is deliberately not before the final typesetting and so forth. And most of us are quite happy with that.

I think the point they've settled on for eArcs works pretty well, overall. But, of course, YMMV. Feel free to wait for a later release. I'll continue to purchase the early eArcs for at least some authors.
