Ever since the WotC OGL debacle earlier this year, Matt has been considering making his own license, but wanted to wait on the work being done on ORC. When I heard that, I was really excited, because while S&W may not be my go to ruleset to use at the table, it is my go to ruleset to write for. Personally, based on what I have seen of the ORC license, it is not something I would choose to use. So, if Matt does produce said license, a good number of the stuff I have written in the past and the stuff I will write in the future will have a home.
Given that Matt was one of the pioneers in the world of retro-clones (he also had a hand in OSRIC), I would suggest going over to Mythmere Games and giving him some support.
