Well most of the main characers are still around (in some form...or playing different characters), it was mostly nameless extras getting shot. Actually I'm now compelled to check the status of who I consider the "main" characters.
Delores - Still alive.
Bernard - Still alive.
Maeve - "Dead" but strongly implied that she's going to be repaired.
William - Still alive (improbably enough.)
Ford - Dead but there's an AI version of him and he's appeared in Bernard's head so likely to return in some form.
Teddy - Uploaded to the cloud, could return in a new body.
Charlotte - Dead but it appears Tessa Thompson will continue to appear in the show as a robot.
Stubbs - Alive/probably a robot.
Clementine - "Dead" but likely to be repaired...really all the dead robots but Angela fall into this category.
Elise and Sizemore appear to be permanently dead (since they're human) and Angela blew up. Also lots of minor characters died but who cares about them, am I right!
So in short I don't know.
