Yeah I'll watch trailers but I have no interest in reading or searching out spoilers, either real or potentially real. I was definitely getting worried that I might see something I didn't want to when so many of the recent posts in the other thread seemed to be talking about leaked stuff from test screenings (especially since when those sort of spoiler conversations go on for any amount of time someone always just ends up dropping the tags and talking about stuff out in the open. I've seen it happen time and time again on many different forums).
As for pronunciations, I've always pronounced it "Ghi-DOOR-ah", even though I kinda know that's not technically correct.
I just prefer how it sounds compared to "GHEE-do-rah". Rodan's just "Ro-dan" for me though. Aint no "dahn"'s about it!
