Good theory about Ichigo's power, I didn't even stop to consider that reiatsu compression was the Bankai's special ability. If that's the case, then Ichigo technically wouldn't have to be any stronger than he was before; it's just a matter of taming the power everybody claims he had all along and cramming it into as tiny a point as possible, apparently to a point of singularity. Now that I think about it, just how much energy does flaunting around your reiatsu waste, even if it's against your will? Perhaps this is showing that doing just the opposite is the true key to becoming all-powerful.
