AJ has just posted the first review of Cauldron #0 issue. THis is available as either an artless, free download or as a print version. AJ reviews the print version and has some good things to say.
If you were on the fence about getting it or just interested in general, head on over to AJ's site and read the review now. More importantly, take a look at the incredible mapping goodness he has created. I am looking forward to working with AJ in the future on some unique HOW materials.
