I don't see why Gwen is going to die, actually. I can't see her playing an active role on the battlefield.

Nor do I believe that Morgana will kill herself - I would find that highly out of character. She'd rather sacrifice herself, or travel to Avalon willingly (which might perhaps be seen as 'killing herself'?).
