Oh yeah the Blizzcon which spoke only about 9.0, since 8.3 is something which wont come out this year, so 8.3.5 will be much further away and announcing another pair without having the current "hyped" pair released, would make much sense. Or we are just ignore that Mag'ghar, Kul Tirans, Mechagnomes and Vulpera were not announced at Blizzcon either.
