PSX Mystery Game?

Sooo, there was a secret mystery game scheduled at 4:00 pm yesterday at the PS Experience event.
I missed the stream since where I live this happened in the middle of the night. As many others, I thought they'd reveal a new game but upon checking gaming sites and forums for news on this, absolutely nothing can be found.

I take it this means that no new game was shown and that the mystery game was something they had already announced at the keynote.

Could someone fill me in what this game ended up being?

Could this mystery game be "Day of the Tentacle"?

The TBA game was shovel knight.

@hatecalledlove: hmm...if that's true, then it wasn't -that- of a surprise. I was hoping for some Morpheus news or perhaps even info about "The Last Guardian"...

I think it was Jaffe's new game. The third person shooter with the paper graphics.
