The sprite has been updated on all servers - the new sprite was overwhelmingly preferred by players on iRO (and, as I understand it, on foreign RO's as well), and people made a big stink about perceived delays in getting the new sprite. I never much understood what the big deal was either way.
I still find it funny how many iRO people vocally complained that the original female Rune Knight was too fanservicey and said the new one was more wholesome, when what Lee Myung-Jin did was throw a flap over the panty and remove all the cloth up top in favor of a metal bikini. (Having his name on the design probably helped sell the change too.)
Most likely jRO and kRO players were the reason for the change, not sure any other server besides iRO had even gotten renewal at that point. Not to mention if iRO players had their way a couple other classes would've been redone too.
