I don't see lever actions as much of a volume or a potential growth market, but Ruger's instincts for the consumer market have usually been correct lately.
Could be good or bad depending on what you like. Judging by part of the internet I see, people who are buying Marlins want more dinosaurs, M-Lok, big loop levers and short barrels, and less blue and walnut. I noticed Ruger discontinued their blued Hawkeyes and replaced them with an all-stainless model with a 20 MOA rail and a threaded barrel. Hmm.
