XII is awesome, talking bad about it is talking bad about all of them. Also XIIIv is an action RPG like Kingdom Hearts.

We wont be seeing anything about XV for at least 5 years I'm guessing, it's taken SE 3+ years to even finish XIII since XII was released, and with doing 3 titles from XIII and an MMO with XIV (which isn't a problem due to the FFXI team working on it) I don't think XV wont be seen for awhile.

AS far what to see in it? Something new, bringing things back is cool but can't overdue it. Job system would be cool but it'll need to be revamped, SE will make up a new battle system. I don't care about what setting though. I'm more interested in Ivalice and what they are going to reveal next.
