Different market?
Honestly, I think that they bundled it in M&M because most of the work was being done by community members, and that was because we're a relatively small market niche such that they didn't face much profit for putting it all in themselves.
Personally, I'm thinking of trying to code things in for these books (I caved and bought some of them in hopes of making some us of them in my 2E games), although I'd prefer to hear what Lone Wolf's plans are so that I can be sure not to step on their toes.
