The role of Hawke and the DA2 party in DA4.

Varric already has a thread, but since Hawke returned in Inquisition and several of the party members have ties to either him, Tevinter, the Eluvians or back with Varric in Kirkwall, I thought it was worth making a thread for all of them. How could you realistically see them being implemented in DA4? Quick Rundown on their possible fates:

Hawke: Survives DA2 regardless of choices, is either still alive and goes to Weisshaupt to meet with the Wardens after Inquisition, or is left in the Fade and is most likely dead. After Trespasser, Varric meets up with him again if he is still alive.
Varric: Survives DA2 and DA:I regardless of choices, ends up becoming Viscount of Kirkwall Probably playing another important role in DA4. 
Isabela: Alive regardless of choices made, even if the player gives her over to the Arishok. Probably plays a signifanct role in either the Qunari origin or with the Lords of Fortune?
Fenris: Alive/Dead depending on players choices or returned as a slave to his former Tevinter owner. Likely freeing slaves and killing 
Merrill: Alive/Dead depending on players choices. Has knowledge of the Eluvians, and most likely she's following after Solas by the time of DA4?
Aveline: Alive regardless by the end of DA2, and as far as I remember is still working in Kirkwall. Probably drinking buddies with Varric down in The Hanged Man.
Anders: Alive/Dead depending on player, Varric doesn't know where he is and doesn't care. I'd love it if him and Fenris happen to run into each other again given their hatred for one another in DA2.
Sébastien: Wasn't he trying to invade Kirkwall during DA:I? Probably on the list of Varric's headaches by the time of DA4.
Bethany/Carver: Either alive, dead or apart of the Grey Wardens. Probably will only get a mention at most considering the three different options present.
