Yeah I was not implying that Kid was dead either, it's known that Oda kills characters very rarely at this point. But I'm saying this is probably not end of the line for Kid in the story. The fact that we're in the final saga doesn't mean anything to me because Oda takes his time when writing this manga, even Egghead arc who we thought to be a short transition arc seems on the way to be a bigger arc, it looks like we aren't that close to the end still.Again, I'm not saying Kidd is dead, just that he's done as a a major player. The difference between now and before is that we're in the Final Saga so there's no need to save characters for future arcs. There's not going to be another Impel Down. It's coming down to the wire.
Law is a different story because he's a D and also has a plot-relevant DF. So I could see him still being important to the story after the BB fight.
But I truly think it's a wrap for Midd when the narrator gets involved Oda usually means business.
Final sagas can go on for years like in Naruto and Bleach so I think Oda will have time to reintroduce some characters I expect it at least.
