Is the trailer itself in 3-D? Otherwise, I don't see too much point in this, but I guess it's cool anyway. I'd check it out for myself, but I can't from here at work.
I never really liked Toy Story. Just couldn't get into it, but 2-for-1, in 3-D, plus the sequel's coming and it looks entertaining (and I need a refresher on the story)...yeah. I could give TS another go round.
I've got the Toy Story: Ultimate Toy Box on dvd and I'de buy it again on BluRay in a heartbeat. Can't wait to see these on the big screen again.
