I also plan on keeping on with 3.5, and will check out this book too.
Having sunken so much time, energy and money into mastering 3.5 I simply cant be persuaded to jump ship now-- particularly with how they are eliminating and redefining so many long standing aspects of the game as weve known it.
I also expect early runs of 4e to have plenty of 3.0 style bugs and typos.
No thanks.
