JuriHDRemix on YouTube is uploading a number of Ruliweb Korean Super Street Fighter 4 videos where you can watch some pretty solid play from both Juri and a handful of other new characters. I've posted up a couple where she gets scraped by Ibuki and Makoto, but you can click this link and check out the rest of the videos where she fares a little better. You'll notice that she has multiple ways to combo into her Ultra, and even though that's not the end all be all recipe for a good character, it's hard to deny at this point she will end up becoming a tough opponent for many players.
If anything, these videos prove that Ibuki will be a real pain in the ass when fighting against any player who has her SJC into Ultra combos on lock. Yes, she has some of the lowest life in the game, but with so many chain combos and mix ups I think she will end up doing just fine in the hands of skilled players.
