Unfortunately, there's no information on those pages about the next design summits of 2014... We can add the information in this page: https://wiki.openstack.org/wiki/Summit ?

I found information about the previous summit on this webpages. I think the next summit will be on Atlanta (USA) but I'm not sure.
