There's already many answers about this in other threads. Last official word from Midoki I think said this week. Picking a day is just speculation, but either tomorrow or Wednesday seems most likely.
No official word on when PH8 will drop. They told us last week that it was definitely not going to be last week.
About that....Do you sword measure often and do you measure up? Note to self never go measuring on a cold day.55555
The update was due in the end of January and it was submitted before Midoki was aware of the stacking bug which those high ranked first found and abused on it.. Thanks to them, Midoki had to fix the problem on priority which delayed the submission. I know you know all this, why asking? The one who had spread the bug out was from the ranked first guild. Those who followed him using the bug are responsible for the delay.
