Ah, but have you seen all of those previews? Those aren't old news...

As far as the G.I.Joe trailer, it looks interesting. But very typical of today's action-film previews. I'm not excited but I'm not turned off by what I saw.
I'm looking forward to seeing the Transformers one at a higher resolution even though I didn't really care for the first movie. I'm sure I'll take T'Igor to see it (he was a big fan of the live-action film).
Out of the three, I think I am looking forward to the Star Trek one the most. While I do not consider myself a Star Trek fan, the original series definitely holds a cheese-factor place amongst my top scifi choices. I know this is a different trailer than what has already been available, but it didn't give me any more or less motivation to see the film.

Tony,
Sorry, but this old news to me. G.I.JOE & Transformers: (Bill, Nick & I) found out at OryCon. Star Trek through another SW forum, talk about irony.
