Pessimist anon was right, no WotL content for the remaster whatsoever. Also
>no new jobs
>no new characters
>no multiplayer
>difficulty selection including a story mode that eliminates permadeath and makes Ramza immortal

On the other hand all classes are being rebalanced and major characters can have new conversations with branching dialogue paths, so it still might be worth picking up. Maybe they'll add WotL stuff as DLC or something.
