I'll buy this book sight unseen, but this preview didn't do all that much to see me on it to be honest.
The neraphim are ok, but not especially cool.
The planar touchstone idea I'm not sure about either. I liket hat small locations will be detailed. That'll be fun. The idea of getting power from them is a bit wierd, and I'll have to have a much closer look before I decide about using it IMC.
