It's good to hear some things are coming along. That said, I have to say I'm really surprised to here that are they throwing the SDK in with the next patch. I think that's a really bad idea. These ought to be very separate downloads/installs. I really don't think too many people, except for a few of us hard-core programmers and those mightily motived, are really interested in having that pile of stuff come down with their next patch.
Anyway, thanks for the update! Hope that everything gets worked out smoothly. If you decide to give us any hint at all on a new estimate for a release of the patch, I promise it will be appreciated (but understand if you don't).
