I mentioned this on the tentonhammer.com forums, but I think that quote is a little confusing, if not misleading. If you read it carefully, it really seems to say:

* 21 product development positions lost, most of which were for unannounced "prototype" products
* some additional Dungeon runners positions

Also, 13 out of 18 Dungeon Runners positions isn't "some", but "most" of the positions on that team. Also, if the grand total RIF count, including Dungeon Runners, was 21, "primarily" for unannounced products, then why were the majority of the 21 positions affected from a single, live product?

Like I said, confusing if not misleading...
