Zero Dawn has no chance to beat it in lifetime sales nor attach rate. Hell, BOTW has already beaten Horizon's attach rate like a red headed step child. 

why would attach rate matter at all? 

Attach rate is the only way to directly compare the commercial popularity of two titles that don't share the same install bases.
