Yeah, and I think they're hoping Watchmen pulls in non-genre people like 300 did and they're hoping Star Trek will.
You know, there is an aspect of this which is about geekdom and overlapping subsets of geekdom.
Basically, it's not just that Trek fans are perceived by marketers as devoted fans of a genre - but that we're a diminishing, older group of fans who are sort of adrift in the larger currents of contemporary pop culture.
Watchmen itself is aimed at a younger (despite the age of the graphic novel), bigger and perceived-as-hipper cohort of genre fans. Exactly the kind of people who they think ought to be a potential audience for Trek but who dismiss it as timeworn, corny and tiresome.
