Has anyone kept up to date with AES modes?

I'm looking for basic mode to encrypt blocks (using AES) of about 1k in length, +/- an order of magnitude. Looking at the above table (2nd link) there are oodles of proposed ones.
It would be nice to have a mode that didn't also require a separate MAC operation - I get the impression that this is behind some of the proposals?
I provide some code and some speed comparison data for some of the AES modes here:

I focus mainly on the combined encryption/authentication modes but I only cover those that I believe are free of licensing costs.
