In regards to the writing at least, I'm still excited for the game.
Mary Kirby, Sheryl Chee, and Lukas Kristjanson are all fantastic writers who have been with Dragon Age since Origins and continue to write for DA4.
If you liked any of the following characters:
Cullen, Leliana, Oghren, Wynne, Isabela, Blackwall, Loghain, Sten, Merrill, Varric, Vivienne, the Arishok, Aveline, Carver, Sera
Then you're still in good hands, as they were written by one of those three.
Those three also wrote many of the classic and beloved questlines throughout all three games.
Also some love for Sylvia Feketekuty, who hasn't been with the series since Origins like the other three I mentioned, but wrote some great stuff for Inquisition.
