If we give the squirrels running in their wheels any more caffeine, they will become "late" squirrels (yes, that's a Monty Python reference). And nobody wants that. We're working on UE as fast as we can.
To put things in perspective, the ARG entailed approximately *six months* of work, and we were able to get started close to three months prior to the release of the book. For Ultimate Equipment, we had barely one month of head start, and in the middle of that month was GenCon, which chewed up roughly two weeks (one week at the Con plus a few days getting prepped and another few getting caught up after return). So we started out in a deep hole with UE, and the book is even bigger than the ARG.
If I quoted you a timeframe, someone here (probably a full posse) would hang me from a meat hook. So all I can say at this point is that the squirrels are running as fast as they can, it's a monumental task, and we're making steady progress. The one thing I can guarantee at this point is that, if we don't have it done in the next two weeks, you'll get lots of details in the September newsletter that outline exactly where we're at with everything.
I wish I had more details than that, but I'd be lying if I said anything more definitive.
