X-men: The Last Stand Easter Egg - Menu Style Toggling

You can choose either the Brotherhood or X-Men menu layouts. Doesn't matter which. Then go to the Features section and hilight 'Commentaries'. Press up. An icon should appear. If you chose the X-Men layout the icon is the Brotherhood symbol, and the X-Men symbol for the Brotherhood menu layout. Clicking this icon toggles between menu layouts. If you're in the X-Men layout it will tak you to the Brotherhood layout and vice versa.
