All the clues are there that Armin will probably survive, whether he reaches clinical death or not first, or has reached it already. The Hange hath not spoken though, so "unknown" is a good tag.

Eren's death is a different story. It makes sense to assume some sort of normal rules until proven otherwise, and Armin now has much stronger plot armor than Eren had back then, being the narrator and the plot device used to pose moral questions. In terms of character development, I think Isayama makes it clear that him having courage is a somewhat minor part of his character, compared to making the kind of commander-like difficult decisions which ultimately sacrifice other people. This sets him apart from Hannes, whose development potential was essentially over by the time of his death. Giving Armin the "warrior's death" doesn't seem consistent with Isayama's objectives and generally doesn't make sense.
