Well, everyone dies eventually, so, yeah, Luffy is gonna die. I doubt that Oda will kill him before he becomes king though. If we assume that Luffy will live to be 50 years old (not a bad estimate, WB was 70-something, 50 isn't that hard), and subtract 10 for the hormones and another 10 for Gear Second, that still leaves him with 30 years of age. He has 11 years to go then. I don't think that he will become king and then suddenly keel over and die, that's my opinion.
