It looks like I'll be able to make the transition to the new design faster than I thought. About 90% of the work is currently done now on a development server - I'll finish the rest up tomorrow or the next day, and will shoot to launch the redesign to the live site sometime on or soon after April 1st. This way it won't interfere with the very last days/hours of the March competition.
I'll make an announcement on the 1st to let you know the exact time of the transition. The site will probably have about 10-15 minutes of "screwy time" while I'm moving files over, so competitive players will want to log out while that is taking place.
