Where did they state that ? 

Дорогие участники!

Мы разметили более детальную и точную информацию об игре: vk.cc/2ejQ1l Свои вопросы можете также задавать там.

Коротко о новостях с онлайн-конференции:

– наша команда разработчиков переписала сценарий от А до Я, сохранив концепт-идею: Без памяти. Мы убрали банальность в сюжете с темой: «похищение сына главной героини» и, тем самым, сценарий стал интереснее, лучше и интерактивнее;

– игра разрабатывается эксклюзивно под PlayStation 4;

– благодаря новому контроллеру от Sony - DualShock 4, управление в Without Memory станет гораздо интереснее. Теперь Вы будете погружаться в игру с ещё большим удовольствием;

– уровень графики будет поражать воображение;

– больше 50 концовок, которые не похожи друг на друга;

– тизер игры ожидайте в этом месяце. Веб-сайт откроем весной;

– съёмки с Motion Capture будут летом. Осенью ожидайте первый трейлер. Релиз игры - 2016 год, второй квартал.
В группе будем добавлять все новости и интересные материалы;

– мы планируем сотрудничать с компанией Quantic Dream, и, возможно, наша игра будет издана совместно с этой игровой студией. Обо всех подробностях мы будем Вас информировать! Спасибо, что Вы с нами!

i wouldnt take today as an actual announcement,  they have been open that they are making a ps4 only game for atleast a few weeks on their social media page.  they have released all these pics and some sound bites,  im guessing it just sorta got some attention today,  E3 is probably the big announcement

I am really interested in seeing what this QoL thing is... Will it be something Jizz Worthy? Or will it be something dry? Hopefully its something interesting or else they should fire the person that comes up with such nonsense

by the way guys to stop any of the BS about paying for exclusivity, they said openly on the social media page that the reason for being console only is because consoles have far greater piracy protection.

This game's announcement was a surprise! But yeah they coulda just waited until E3. Perhaps they were afraid of it being overshadowed by other big game reveals.

Who's the publisher for this ? Is it Sony or is it the studio's themselves ? 

The post is already some months old and as much as I understand it does it mean that they "want to work together with Quantic Dreams and they could be even the partner to publish it"

English please

well, here is what google says (the post is almost three months old, some stuff could have changed since then):
