So I was talking to this NPC in Uldah today, Orrick and he said:

"Hm? What goods are in vogue among upper society at present? Without a doubt, that would be ceruleum-driven magitek devices. If I might speak plain, such devices as seen in Eorzea are merely glorified playthings beside Garlean technology...but let the rich have their playthings, I say!

While we're on the subject, my sources give me to understand that a plan is in motion to lay a magitek railroad across the wilderness. Should this knowledge bring you into wealth in the future, remember to whom it is you owe your good fortune."
Does this mean we are getting a railroad in 2.0? That would be cool. Alternative way to travel!
