New KSL's are obviously a totally different shoe than the original, so they should just release it as a new shoe and not try and say it's a reissue. If they just said that's a new model and didn't put the stripes on the side, that's just a nice simple cupsole with (I believe) that good pour-in G6 midsole.
I don't have any nostalgia for the original ones, so to me that's just a new cupsole that I'm interested to try. I like that sole, but I don't like the uppers on the shoes available with it currently.
