MB Trading Commissions Getting Even Smaller In Sept?

Has anyone heard anything about this an MB Trading making their commissions even smaller? They just posted a banner on the homepage that could hint at this. If anyone has any more information let me know as I use them as my main broker of choice. This could be good for clients :). Although… the commission is very small as it is, will this make their business unsustainable in the future? Who knows… Any thoughts?
