I am, aside from waiting for BG3, currently interested in Starfield (once it got mods) and probably DA4 (if they don't completely mess it up).
But to be honest, Starfield is not really something I see as a competitor for BG3, they are too different. It feels to me like saying Warcraft 2 is a big competitor for Heroes of Might and Magic, since they are both strategy games. Way too different, scratch a different itch.
