I dont think any news outlet reported on this

Take-Two sent a TEAS Extension request to the USPTO (United States Patent & Trademark office) and it was received by USPTO on 24th November 2014.
(Check references for links, and check Prosecution history)

I aint no legal expert, so I had to google what a TEAS extension is. (im british so the first thing I thought of was PG tips, but no)

Through a google search, it is a request (or more formally called a petition) to revive an abandoned application, or for a time extension to prove it's active by presenting a 'statement of use'

AFAIK, a company cannot keep extending a trademark if they have no visible product or outcome from it. I may be wrong though.

[1] The United States Patent and Trademark Office (USPTO) "abandons" a trademark application whenever the USPTO does not receive a timely-filed Statement of Use (SOU) or Request for an Extension of Time to File a Statement of Use (Extension Request), in response to a Notice of Allowance. 37 C.F.R. §2.65.

Probably not a PS exclusive anymore. Sony might have swapped this deal for GTA V marketing

I refuse to get my hopes up.

that sounds like  a bad swap lol. they'd wanna get exlusive  heists thrown in or something. 

Sony E3 2015:
Andrew House walks on stage, says nothing, points his finger at the screen and walks away. Rockstar North's logo appears, followed by a trailer for Agent. PS4 exclusive, early 2016. Andrew House isn't seen until 40 minutes later. He walks onto the stage again, points his finger at the screen again and again walks away. Naughty Dog's logo appears, followed by a Crash Bandicoot trailer. Release Q4 2015. Fast forward to the end of the show. Andrew House walks onto the stage for the 3rd time, points his finger at the screen again and walks away again, all while he hasn't said a word yet. The Last Guardian trailer is shown, followed by the end of the show.

Believe!

I will only believe it after they announce it

link to that crash trailer you talk about>? 

Nintendos revived the eternal darkness trademark a few times now. Doesn't really mean much, just that they don't want to lose the trademark.

I wouldn't too, but at a factual level it means, at the very least, take-two intend to release a video game called agent as some point.

They've owned the trademark for many years, and they have to prove they are making a commercial product out of it, otherwise USPTO will take away the trademark.

If agent was dead in the water, take-two would have no reason to keep renewing and extending the trademarks.
And we know they are showing some form of evidence to USPTO that agent is intended to be a product.

So believe..

Eternal Darkness afaik is a physical item/game that has released. So they own that trademark and have the rights to renew it as long as they want.

USPTO dont want trademarks to be kept if they are not made into something, be it a service/product.
Which is the whole point take-two request the extension
