Instead of addressing questions about multiple individual RPG systems, I'll outline our overall philosophy/strategy. This should provide guidance regarding most titles you can think of, although there will almost certainly be an exception or two that arise along the way (there always are). 
1. Our initial focus is on the larger RPG systems (e.g. World of Darkness).
2. Once we've got the majority of those in place, we'll be focusing on the less widely played RPGs that have strong player bases and could benefit greatly from HL.
3. We'll also be working with some of the smaller RPG houses to enable them to develop their own data files for their games - with our direct assistance. Discussions about how that will work have already begun with a few of the smaller houses.
4. We have no plans to do any work ourselves on out-of-print and/or "niche" RPGs. We're simplifying and streamlining all of the tools we use in-house for data file editing based on everything we're learning with the first few licenses. When we finally release the tools for users to create their own complete data files, users will then be able to develop the files themselves for out-of-print and/or "niche" game systems.
Note: Please don't ask for a date on the tools for creating a game system from scratch, since we don't have an answer for that yet. My hope is that we'll be able to provide an answer to this in October, after we've got the WoD and M&M files out (and have completed the learning cycle from those games vis-a-vis the tools).
Hope this helps,
Rob
