Some answers to questions.
1) Timeline. No, we didn't have these under consideration until now (other than planning to make most of our game setting available for play in other systems over time). Savage Worlds came up sooner due to an opportunity to have a direct conversation with Pinnacle -- and the fact that they are such nice and professional people.
2) There is no set order of release. Demonworld is noted as we are working on the next edition of the miniatures rules and it does not have an associated roleplaying game with it (and we wanted a miniatures-friendly system to go with the extensive miniatures line). Earthdawn is high on the list because our core game line has been out for a while now.
Hope this helps!
