Earlier today, Brian announced updates with responsive design. Today, Nick from Elegant Themes, announced the preview of Evolution. There is a clear pattern that responsive design is the next generation of design.
Evolution looks to be a clean, image-centric theme, that lets you easily display portfolio items. Big slider in the header for photos and a crisp menu style up top.
One thing I would really like to see more of, is the ability to go beyond the standard menu style. The Mega Menu plugin by Design Chemical, is a great way to really separate yourselves from the competition.
