Actually I think it is fair to say that various European martial arts are undergoing a widespread revival. As general categories there is longsword work, which based off of the currently translated treatises may be split into a couple of nationalities.
These treatises cover alot more than just swords, wrestling, dagger, are all part of these systems of martial arts.
Besides longsword are people working on the sword and buckler forms from I.33 and some other sources.
Most of the treatises have not been translated, so just how much material is out there is unknown. What I like about the European manuals is that they are very explicit and generally good illustrations. Of course these motions are open to interpretation, but I think it is alot easier to understand these, than some rather cryptic explanations found in many eastern texts.
Take a look at the previously mentioned ARMA site, it is the largest of the Western martial arts associations out there, and a good intro to the topic.
