According to Hecker in his blog, "The new art isn’t very playable yet, since we only have the five characters so far, and only a subset of all the animations even for those. John is working away furiously on getting statues and books and drinks and briefcases and everything else supported by the new folks, and then he’ll move on to do the next batch of characters. It will be a while before the new art is tournament worthy.”
