Steve Meunch just announced it on his weblog (http://radio.weblogs.com/0118231/) that the guide is now finished.
"The birth of a "baby" they've been working on for many months, the ADF Developer's Guide for Forms/4GL Developers. You can find links to the HTML Format and PDF Format of this new guide on the new ADF Learning Center on OTN.
