Yeah, I can confirm that Mongoose is no longer sending me stuff. It's a pity, too, since I really enjoyed a lot of what they produced. (If you look at my reviews of Mongoose products, there are several "5-star" reviews in there, and I gave out a "4" rating many more times than I did a "3" or a "2.") The last time I contacted them with a "wish list" of products I'd be interested in reviewing, they informed me they were reworking their review process, and I haven't heard anything from them since. Fortunately, about that same time, JoeGKushner recommended me as a staff reviewer (thank again, Joe!), and I started receiving products from a whole bunch of other d20 companies.
That said, I'd certainly be interested in taking a look at Mongoose's new monster books. It sounds like they did a great job reworking their quality control process (according to several posts by Matthew Sprange himself on these boards), and I'd be willing to bet that their monster stats have improved significantly since their Ultimate Monsters Volume 1 days.
