I'm sure some of you already know this, but I'll recap:
So the update is on the servers currently, but hasn't been sent out to Wii U consoles and such just yet, so while there could be the possibility that the patch actually isn't completely ready and/or the full update is not together yet on the servers and it's just part of the patch, it's best to give up on hoping for anything in case anyone actually was. According to Random Talking Bush and a couple others who have been checking the data, the only changes are Bayonetta nerfs as far as characters are concerned (there are apparently unknown changes to Stadium and Palutena's Temple so far as well).
In short:

We'll find out for sure when it officially drops, obviously, but for now, nothing to see here.
