I didn't, actually. Didn't have any physical books to sell. I'm looking to get some books into dist soon. Not sure all the details yet.
If I can get into a pre-release group on 4th edition, I'll need to do some sort of big release as soon as we're legally able . . . that would be for a 4th edition version of the campaign setting and it would require me to play catchup with products 2, 3, etc. as quickly as I could. Luckly those books are all fairly rules light . . . the longest part of most of the conversions will be the NPC (except for product 4 of course, the nightmare product
). Also, I have plenty of d20 people in the company to help pound on conversion materials.
That can't hurt ICE and HERO games, either. I think, actually, that all companies benefit from a multisystem product, if the product is interesting enough on its own. If you like Echoes and you bought it for D&D, and someone has been trying to get you to try HARP, you still have the comfort of using the same setting. If you like HARP and D&D, you probably buy products for both systems, because they only have to keep up on one setting between them, so that lowers the entrance cost considerably. (And they can get PDFs for all versions fairy cheeply and just buy a physical Echoes book for the system they play most).
At least that's my theory.
