Word is that there will in fact be no LE or Premium Star Trek Machine at the expo this year. (Of course, this may be false statement itself, as Stern is known to keep secrets, etc). What I heard was the one and only look/view of a real life Stern Star Trek LE will be at the actual Stern Factory Tour Thursday Morning. If you dont see it there: you aint gonna see it. Also, that particular unit is not for play, but will be powered on showing off the lights, etc. No-one will be allowed to touch it.
We shall see what is true in about 8.5 hours. I will have my DLSR with me to document whatever it is that we see, even if it is nothing. From there it will be on pinside very quickly.
