This is a 13-minute trailer for Final Fantasy XIV: A Realm Reborn with Japanese narration
If there is anything that could possibly represent the merging of MMO and JRPG better than a 13-minute-long trailer featuring narration I can't understand, I can't fathom what it might be, and I say that as both a regular MMO player and a guy who bought Atelier Totori Plus from the PSN today. In any case, here is 771 seconds of moving images from Final Fantasy XIV: A Realm Reborn, and if you understand Japanese you'll probably find it very informative. Otherwise, just enjoy the pretty pictures.
This reboot officially launches August 27 on PC and PS3, and pre-orders get early access on the 24th.
