Just talking new stuff published specifically for clones.
I'm guessing Labyrinth Lord has the most published support at this point. There have been a lot of releases for this system over the winter. I think it's pretty cool just how much people like this game, even though it's not my preferred version of the rules.
OSRIC likely comes in next, as it seems there is a new module for it every month or so. I have no real interest in OSRIC or 1e anymore, though, but I'm glad those who do get lots of new adventures.
S&W gets a fair amount, especially with Knockspell.
Brave Halfling and Lamentations of the Flame Princess have really done some good work for all the clones. I hope they continue to be successful, though I'm aware LotFP may be switching gears to supporting Jim's own ruleset.
