I think the intention of the author is to release a 1.1 update. If it is anything like his previous updates it will be a couple of pages of things like 'p20, 2nd para, 3rd sentence, line 6 replace "with" with "not with"' or something like that.
As he mentioned on the yahoo list, it will clear up some language, fix typo's and "boo-boo's" rather than a new edition.
If it follows previous patterns, when they runout of printed rules, Phil will incorporate the update and then change things for a new edition. I suspect this will be sometime much later.
