From what dulfy has posted on her website with all the pack content and other amazing things. My educated hopeful guess will be that the pack will come with this update or very very soon at least. They don't normally give pack content and then wait ages to release it.
So it's looking hopeful
I asked this last week ALREADY , NEVER had any official answer... MY guess it it will NOT come this week either :-( (yes i also wait for Veractyl and Mandalore armor..) but next week, there is NO info like normally on new CPack on the official website which there has always been the day before patch. In fact its been VERY quite from devs last couple weeks, my guess they all in holiday and the ones still left in office play Arenas on PTS.
P:S Also this is now officially the longest there has ever been between new CPacks... it must be for Vacation period reasons.....as i mean Cpacks is what feeds this game and keeps the lights on.
