Compared to standard unit awakening, what is the difference? And any ideas when we will get it?

We need max level(?), max skill levels, max affection, 3 silver CCed/Gold units(?), 1-3 AW orbs or some new SAW orbs(?), 200.000-300.000 gold(?)

Just awakened my waifu so i wanna get ready the moment it comes live:

Also, is there something like special missions for characters to unlock their 3rd scene? If yes, when do we get those in case there were any rumors?
