Yes, there are the Alpinis from Waterloo, and I missed the announcement from Roden. GB Modelli's stuff looks great but it's always been a little bit out of my price range. Germania only seem to make German subjects and (probably like everyone else) I have a ton of German stuff. MGM recently released two LK variants, but again, I've already got every German WW1 tank kit/model.
Back to the Chasseurs, if they were done in 1/72, it looks like it wouldn't take too much effort to make them work for WW1.
As Peter the Great said, these are a re-release of one of several WW II french infantry sets in 1/35 that Heller first produced decades ago. In 1/72 such a set would work well for both world wars, although weapons would be a stretch. Another set missing in 1/72 would be dragons portee for WW II, with their specific helmets.
