Yes, I've seen it.

A top secret, unedited version of a scene from the upcoming prequel.
It went like this:

After dimming the lights in a former Desilu screening hall, an insider
guy started the projector for a small group of internet/reporter
types. Out of the darkness, we see the outlines of the Cal Northridge
campus, now fully transformed into a Starfleet Academy (built some
time after the events of the Enterprise series) which is enshrouded in
night.

Scattered, futuristic poles cast small circles of sparkly light in the
large courtyard. I must say, the effects in this part are truly next-
generation stuff. It's so foggy, and so dim, that it's just like
standing near the San Francisco waterfront in the midst of dense pea
soup.

As the scene continues, the camera follows this new guy playing Kirk;
whom I have to admit is a carbon copy of the original character.
Suddenly, he seems startled by something. The few lights in range seem
to be going out, one by one. Each time a light goes out, it's preceded
by a narrow, almost imperceptible beam of light. We guess that
somebody with a phaser is blowing out the lightbulbs(?) one by
one...but why?

Kirk stops, all senses alert, scanning through the dense darkess for a
sign of something, anything at all to explain what's happening.

"Thud", the speakers seem to thrum out in a room-shuddering instant.
Young Kirk stumbles, but quickly turns to fend off the second blow.

"Ahh. Jimmy, me boy," comes a loud Irish brogue. "Good, but not quite
good enough, eh?"

Out of the mist, with a rasping crack, whips a large stick
