Direct from the FIRST website:

FIRST has begun to receive questions about plans for the regional events and Houston championship should an act of war or terrorism occur in the next months. We are concerned for the safety and security of citizens facing these threats anywhere in the world, and, in particular, for all men and women in the military.
While we recognize the impact these acts would have, we also understand the best course of action at this time is to continue to move forward with the existing plans. Therefore, FIRST is continuing to follow those plans and do all that is necessary to deliver superb regional and championship events for all the teams. We are not considering cancellations, extensions, or refunds. We do recognize the right and responsibility of each individual to judge how best to proceed. In the meantime, we'll continue to work toward a great season of Regional events and the Championship.
