Guessing the character silhoutte from the newest dissidia
So it looks like the setting is in modern world and of course the map is Tokyo
The majority of character silhouettes are OBVIOUS and there are some hints if you look at the white dots in each location. And if you are listening to the BGM, there also a total of ten tracks from ten series, which match the total of the ten silhouette. So I'm trying to make a guess before the announcement in October 14th.
Kain. You must be surprised that why the one with hat is Kain but looking at the shot in the Tokyo scenery, There is someone stand on top of Tokyo Tower and there is only one FF character with this iconic pose. And one of the battle BGM is from FF4, A mix of battle theme + Main theme
Terra. it can be seen by the wavy ponytail and the pics with moogle plushie and crane game. Terra loves Moogles.
FF1 WoL. The hair looks like him without his helmet. IMO, the pics with boots giving a vibe of a hero who is going to start their journey. I think i've seen this similar shot before though i couldnt remember.
Lightning. Obvious silhouette. The white outfit reminds us with the outfit she wear in the ending of Lighting Returns. And if you look closely, She wear that looks like a sweater beneath the white jacket. You can see she is also wearing short(?) with belt in the pic with the "Artemis bag". This two is probably based on Lightning's Guardian Corps uniform. (the turtleneck and miniskirt)
Rinoa. Another obvious silhouette with that finger. If you see the shot, you can see a girl with black shirt(?) with double ring necklace and blue cardigan.
Either Gaia or Ryne. This one is difficult but "Return to Oblivion" plays as the BGM so it is one of them. The "Artemis" black shopping bag and especially fishnet stockings, IMO fit Gaia better. but "Return to Oblivion" fit Ryne better. What do you think ? I dont play XIV so i dont have much knowledge about it.
This one is also a bit difficult but i think it is FF5 Krile. I was a bit surprised with the twin pigtail since it is associated with Vanille. But the accesories(?) like a cat's ear one reminds me with Krile's costume as White Mage. As for the pics with birds, it is perhaps referencing the wind drake or how Krile can speak with animal. By the way, Krile can be associated with the moogle pictures since she keep a pet moogle. The BGM is based from when you ride the Wind Drake.
Cloud. The hair and the bike is OBVIOUS, isnt he ?
Zidane. There is some people talking that he is FF13-2 Noel since the silhouette look similar but it is clearly Zidane by looking at the pictures of a flyer with a man and dog. There is a word ""東京演劇祭" , "Tokyo Theatre Festival" and "新宿アレクサンドホール" (Shinjuku Alexander Hall). Zidane is associated with Tantalus Theatre Group so it is definitely him.
Prompto. Another OBVIOUS one, especially that gun and hair. And the pics with camera. If you look closely, this man's outfit has the same pattern with Prompto's shirt.
And here is the BGM that can you heard in the teaser site.
