Well, some people don’t like older animation style, they feel it’s dated compared with more modern styles. Also, the true ending was never animated, it had an anime-original ending which is not canon. So I guess there’s the possibility of remaking the series and finishing and staying true to the manga. Also, hopefully with less filler.

I agree that the original still holds up, though, but I’m guessing (and hoping) they’re trying to do the whole Fullmetal Alchemist: Brotherhood treatment to Rurouni Kenshin. I’m mostly interested in watching out of curiosity, though.
