Two months in optimizations and bug fixing with so many content and mechanics is like saying you gonna climb Everest after lunch and be back for dinner, which you'll bring. What i don't like about this news is the set-in-stone date which i hope is not the case, cause it is not gonna make it as polished as it should, and if you stayed around you know how it is with eta's and bugs after every update.
So to me it would be fatal for Ark to release the game unfinished after all this, critics would eat it alive and people would bury it. I do not want that to happen that is all.
