It can of looks like Renji's shikai has changed from a 6 segment sword (has par his wiki page) to a 7 segment sword. Plus the end of it seems to have a point on it now and not a smooth curve. But we only see 2 panels that really show his shikai and even those are only parts of it so we will have to wait and see.
