-SC2 there is nothing new (new coop yay)
-HotS there is nothing new (new banners, FUCKING YES!)
-HS gets a new expansion like always
-Diablo Mobile announcement was infuriating
-WoW does as WoW always does when there is no major expansion coming up (new patch, "we're gonna fix the expansion", new raids, new dances...). Some things are actually good
-Classic demo is also super meh
-I'm out of touch with Overwatch but yay new heroes
-WC3 Reforged is the only kinda exciting thing and it's a remaster... would've liked a complete Warcraft RTS remaster more (WC+WC2+WC3+all addons) but I'll take WC3r
-Cinematic and art is good as always
-Esport is also good, but you don't need a Blizzcon for that
Back in the day Blizz would skip Blizzcon if there was nothing major to announce. Should've skipped it this year.
