Super tinfoil hat time
What if Blizzard is intentionally tapping into the meta for this one?
They randomly pick a fake leak that's rarely being considered/talked about, they take that name and register it on their site, and they also create some throwaway 'promotional art' with a fake logo on reddit to throw everyone off the scent.
Think it's possible they're conning us with this one? Like they intentionally might know someone would try and datamine the website so they purposely throw a red herring our way?
