So, BioWare probably isn't going to be making a new Dragon Age game any time soon—maybe ever, depending on how things go. After Dragon Age: The Veilguard underperformed, much of its team (including senior members who had been making Dragon Age games for a while) were shuffled around or laid off.
This isn't necessarily out of nowhere. As quite accurately called by consultant and former BioWare vet Mark Darrah, almost prophetically, this marks the first time the studio's only had one major project to focus on.
He rather optimistically stated that these devs would find their way to other EA studios, and that the challenge would be involved in trying to get them back.
Turns out, he was partly right: A lot of them are just gone entirely. Regardless of my thoughts on the game's writing, plenty of the staff now departing have made good stuff in the past.
Trick Weekes, for instance, wrote freaking Mordin in Mass Effect 2 and 3—as well as Iron Bull and Solas in Inquisition, two other characters I like very much.
