I never noticed any of those, though was the Fontaine Futuristics Logo not in Bioshock 1?

Regardless, Ryan was clearly responding to Suchong in that recording, it would seem strange that he felt the need to respond as such to a dead man. The pheromone suggestion only makes sense in an environment where almost everyone is spliced anyway, like Civil War Rapture. It wouldn't make sense for Suchong to suggest it beforehand.
