Did they do one of these last year, if so, was it any good?

Also, isn't it on the same day Mayweather is pencilled in to have a fight - September 13th.

There was something like this advertised when I was in vegas for Mayweather Guererro, but it didn't come off. At least not to my knowledge, and I went out of my way a few times to figure out what was happening.
