They're both NCSoft games, so I am pretty sure that Anet took some inspiration from Blade and Soul when designing their gliding system. If you haven't seen "Windwalking" (aka gliding) in BnS, yet, here's a couple of videos that spotlight some new "wings" that China is getting. Wings aren't gliders, they're just cosmetics. Gliders, or any equipment, are not needed for windwalking. I expect NA will get same or similar, sometime after it launches this coming weekend.
(Windwalking is just freaking awesome and does require some practice and experience, which makes it a lot more fun and controllable than most other glide systems.)
