What I took from everything released so far is to expect some sort of shout-out to previous FF titles. We have the warrior of light helm, the obvious buster sword reference as well as golden saucer(ff7 duh),the ff6 tribute of Terra controlling magitech armor, and then them joking about Lightning. I myself am expecting plenty of either references to past FF titles or vanity items commemorating them but my only basis for saying such a thing is the fact in the last FFXIV trailer they started it off by showing clips of FF1-FF13. Maybe it's wishful thinking but I myself will be looking for those references in ARR once it's released. How about everyone else?
