If Sony wants to end the conference for die hard players with a bang obviously they'd have The Last Guardian shown, with a demo, on PS4. But you won't get a leak of that until minutes before it happens (on twitter or whatever). The team would be so small they could keep it uber secret until then (a big ??? on the itinerary with journos asking around and finally getting a solid hint minutes before the reveal).
At that point it won't leak. People are paying so much attention to the show that those who can leak it or those who will read it won't get the surprise spoiled.
Plus GAF is more often than not, the source of leaks like this, and it will probably be down, so there's that too.
