A while back, Dengeki had an interview with Naoki Yoshida and Satoshi Sakai (the director behind Phantasy Star Online 2), and I believe it was said that, if possible, they wanted to do some sort of collaboration. Recently, players on PSO-World (and later posted to Reddit and Bluegartr) discovered images of FF14 relic weapons in their latest patch for PSO2.

My question is, can you explain if Yoshida and Sakai were finally able to have some sort of collaboration, and what can we expect to see from PSO2 to come to FF14? Also, are there any lore implications behind this?
