Could it be Indigo Prophecy related? 

The teaser image certainly fits with the box art.

Possibly rebooting the franchise, or completely remaking the title? I believe David Cage mentioned that they were very constrained during development by hardware limitations with Indigo Prophecy.

Would like a reboot of Indigo Prophecy, never got around to playing it before.

if they did remake indigo prohpecy,then at least its older than a year

Yay! I hope it's a reboot, or an improved remake, of Indigo Prophecy. Always wanted to play it but never had the chance.

It would give a good taste for QD fans before they release their big game later on PS4.

Never played it, but will surely try it. I am a big fan of the genre, and loved Beyond 2 Souls. We need more games like that.

Man... Im really excited.

So the january announcement doesn't seem to be a simple Beyond Remaster, wasn't there a pretty big thread with people bitching about that a couple weeks ago?

That twitter account is not from QD, it's a fan community. But it might still be related to QD

Yes. It's a rule on the internet that you must bitch about a remaster only if the original game came out 1-2 years ago.

Anything after that is okay!
