I'm saying they wouldn't treat it any differently. The CSI: New York and CSI: Miami shows are analogous to New Avengers and Might Avengers. To have a similar analogy with Decimation, you'd need something like "Tonight on CSI: New York: The Night Stalker!" and then the same tag for CSI: Miami. That would make someone think they had to see all the CSI shows to know what this Night Stalker thing was.
