For the exact wording:
As for anything released at gamescom, it will be made immediately available for the public. No worries there!
I think the key word is released here. The extended trailer hasn't been released. Kinda the opposite, kept captive.
All in all, it's not the biggest deal in the world. They've followed the letter of what they said, even if not exactly the spirit of it, and that's perfectly within their rights. Especially when they do need to play the media game, and give the press something to chew on.
As for it leaking out via phone, if it hasn't already it's not gonna, not by the media or Peter. The only way it would have anyway was if YSnet were okay with it, and if that was the case they could maybe have released the whole thing in the first place. If the media secretly films it, it's a breach of integrity and could get the leaker fired. If Peter films it, it's a breach of the trust of Yu Suzuki so he's obviously not going to do that.
We'll have to live without that extra minute & change for now.
We may get a treat by the end of the year according to what Suzuki San says in this interview:

Tout d'abord, j'aimerais savoir pourquoi vous avez choisi de ne diffuser qu'une version raccourcie de la vidéo que vous venez de me montrer ? Est-ce une question de marketing ou une éventuelle exclusivité pour les soutiens de Kickstarter ?
First of all, I would like to ask why you've decided to publish a short version of the video you have just shown us? Is it a marketing strategy or maybe it's meant to be an exclusivity for the Kickstarter backers?
Il discute un peu avec son traducteur, également responsable de la partie business d'Ys Net, qui prend le relais pour répondre) C'est une bonne question ! Il n'y a pas de raison particulière, honnêtement, mais certaines personnes pensent qu'il est un peu tôt pour montrer la version longue. L'idée derrière ce teaser pour la gamescom était avant tout d'accompagner l'annonce de notre partenariat avec Deep Silver. On voulait surtout montrer qu'on a désormais un meilleur soutien financier, que l'équipe est prête et que le projet avance. Nous sommes restés discret pendant trop longtemps et je trouve qu'il était important de montrer quelque chose pour ce salon, sans que ce soit une véritable stratégie marketing.
Yû Suzuki (en anglais) : Peut-être qu'on va réaliser une version plus peaufinée et plus longue de cette vidéo pour la fin d'année, un vrai trailer promotionnel.
... (I'm not translating the first part since it's basically something Yu did explain already about the fact that the teaser was meant to show they are making progress since they were relatively quiet since then and it was to come with something substancial now that they have signed a deal with Deep Silver.
There are also people within the team who think it's too soon for showing the long version of the trailer.
Yu Suzuki (in English): We may create a longer and more polished version of this video for the end of the year, a real promotional trailer.
Place your bets... PSX, Christmas backer update?
PS. If you are interested in a translation of the rest of this interview, I can do it tomorrow morning ;)
