Unnessesary info on articles

So recently I have been around this wiki and I noticed on alot of articles (Most noticably batman) that there is alot of info on those wiki pages that have not been confirmed. Most notably in Batman's early life section. Sure I'm sure most of it's true but with the trailer we've seen none of this info has been confirmed by anyone at warner bros. So I feel we should delete all this unconfirmed info out of the articles until the movie comes out.
