With a tail you can almost justify the inclusion of a cockpit for a pilot, but it looks a bit ugly having a bulbous cockpit on the flying wing. Here's hoping we keep tails! :)
I hear more and more hang glider pilots are putting tails on their HG's because the performance difference is small but the added pitch stability improves safety considerably (and probably lets them then push the limits further). There was an interesting thread about the NASA prandtl glider on rec.aviation.soaring with some armchair aerodynamicists chiming in both for and against, but I can't find it now....
