I thought that. But apparently he later clarified that it was an event specifically referenced in TOS. What's most confusing about the information we have so far is that Fuller said different things to different people, worded differently, which were then interpreted differently by different news outlets. Look at 'female lead' versus 'female captain'.One thing i'm not sure anyone has noticed is that Fuller never quite said the "event" in question was referenced on TOS specifically. His actual quote is below.
“There’s an incident and and event in Star Trek history that’s been talked about but never been explored."
This leaves a LOT of room to guess. Could be any event referenced in any of the 5 series.' If I had to make a shot in the dark, i'd say Station Salem One, if only because it's something that i've always wondered about!
Given the rumor that there's a Klingon in the cast, could Station Salem One be the "bloody pre-amble" to a Klingon war with the Federation?
