Well, well, well. Ichimaru's bankai is actually really good as opposed to what I thought earlier. It has many implications, but he will probably get kuboed. Hopefully he won't since he is my favorite character. This ability does bring into question of why Aizen let this battle drag out so long when Ichimaru could have destroyed all four pillars on his lonesome.
On a side note, anyone think it's possible that Ichimaru may have split the other pillars and they are just falling in slow motion? Like dbz slow.
