mx: I should point out that the non-review I did was really a non-review. There are a number of minus points about the book as well (for example, the author kept reminding the reader of how good he was in a non-obvious fashion). So if On Game Design is as expensive in your area as it is here in .au, you may wish to borrow a copy.
edd: Hopefully your prediction about the lack of new standards will not lead to a dying off of articles at xml.com. I really enjoy the articles there that talk about new and ongoing uses of existing standards. For example, Kendall Clark's articles, which often cover the bridging of the gap between commercial and more theoretical and general XML usage, are food for thought. As are a lot of the others.
New standards still have to prove themselves. Existing standards which are being used in commercial and non-commerical settings are already showing their resilience and articles which help reuse are encouraging.
