I would be very amused if they knew the name would be public through SteamDB and they used this as a placeholder name to obscure the real name of the expansion. :-)
I mean, Secrets of the Obscure? Might as well be called The Place of the Holder. But then again, who knows. As long as it's not another Guild Wars 2: Remember That?, I'll be happy.
It looks like ncsoft's attorney filed a trademark on Secrets of the Obscure in March using a shell company called Secret River Enterprises. It's the same attorney that did other GW2 trademarks. They also did not prefix the trademark with "GUILD WARS 2: " like the other expansions.
So I don't think it's a placeholder, unless they're really committed to fucking with us.
"Secret River" and the "Secrets of the Obscure" give me some River of Soul vibes...are we perhaps going to the Underworld? It's supposed to be under new [demonic] management now, right? And we just had to deal with a demon in Gyala Delve...
I don't remember anything in guild wars being referenced as "the Obscure" before, right? Must be something completely new, possibly related to the void? I'm still more curious about the date and gameplay improvements over where the story goes next but nice to see that something's cookin'.
