As I understand it, Remington owned Marlin, and Remington went bankrupt recently and was acquired by Sturm, Ruger & Co late 2020. Combine that with covid, it's unclear whether or not they're making new rifles at the moment, so I believe that's why there's barely anything new available online. I imagine they'll show up eventually, but might be a bit of a wait. I'd like a Marlin Dark in .357 myself.
