I think they could show too much - but it's a very subjective line.
The cyberdisk for example. I love the new look and transformer aspect - I don't
mind that they showed it but had my first experience with it's 'transform and curl out a grenade' been during the game it would have been an OMGWTF!! moment and would have thrown me into a defensive turtle for a mission or two while I watched to see what ELSE it did now.
I'm going to hazard to guess that there WILL be some OMGWTF moments for those of us who played the original. That there will be a few tweaks and new aliens/experiences that keep us on our toes.. and I DON'T think Firaxis will show them to us before we encounter them.
The week I get the game, I'll be completely avoiding these forums or any other webpage that might contain any sort of spoiler. Heck, I may just unplug my ethernet cable for the week.
