Actually, it's from an interview with Nomura in S-E Members site:
Nomura confirms worldmap/airships on worldmap, but doesn't give a percentage done for Versus XIII.
From evil_maki on gamefaqs:
1. Current progress of games you're currently working on, games currently playing and non-gaming hobby?
Nomura: I want to release two games within this year. Just recently finished "Battlefield 2" and started playing "Heavy Rain". For other hobbies, I try to watch all sorts of motion pictures.
2. I would like to know the current progress of Versus 13, Agito 13 and 3rd Birthday, and also when new information will be revealed.
Nomura: Producer Hashimoto isn't letting me.
3. You used to be on Kojima (Hideo)'s net radio for awhile, but how are things between you two now?
Nomura: Sometimes Kojima invite me to lunch.
4. I would like you to start using Twitter.
Nomura: I have... nothing to tweet about.
5. I'm curious over what happened to your consideration over a Dissidia FF sequel!
Nomura: I'll try my best to work on Dissidia FF's sequel!
6. Until of what age do you think you'll be actively working in this job?
Nomura: I haven't thought much about my future.
7. How much percentage of Versus XIII is done so far?
Nomura: Not everything is connected yet; each part of the game is progressing differently. Oh, but we got the airship to fly on the World Map now.
8. You've done all sorts of character designs for FF, KH, Parasite Eve, Subaseka and so on; who is your most favourite?
Nomura: I like all of the characters I created but Sora is the most special because of the many associations he brought to me.
