If you're not told/promised anything for when the countdown ends, you need to not be disappointed when there isn't anything.
i mean
sure it wasn't directly said that we would get something but there were countless official teases and clues and stuff leading up to all this
regardless tho there was a lil something that we got anyways and it'll likely come at blizzcon or something but i'm still wondering why they manipulated the countdown during it to end on tuesday, the day that they release stuff on, instead of monday if they're not gonna actually release anything
