I don't want to miss another deadline...so I just won't announce the deadline.

I think it will be an April release, based on the rapid progress that's being made, but there's a reason the web site just lists "Spring" at the moment. As soon as I can commit to something solid I will announce it. I've incorporated many of the suggestions from the beta rules, including some of the time-consuming ones (like unique misfire/corruption results for each spell), and, well, they took some time! But the final result will be worth it.
As for the pre-order special offer, anyone who pre-orders will receive a unique module that will not otherwise be available in stores. It's a full module, not just an "insert" - full-color cover, 16 pages, written by Harley with art by Doug and Stefan. Separately, there will be an alternate gold-foil cover. The alternate cover will be produced in a limited run and will cost a little more (the printing is more expensive). You can pre-order either version and get the module, as long as you place a pre-order. I'm planning to announce more details on these in a month or so when I have a near-finished layout in hand and can really commit to a release date!
