That's the news according to Brad Fuller's blog. Those who were at Comic-Con 2009 were treated to what has been alleged as an "incredible" teaser trailer/footage from Nightmare on Elm Street 2010. Fuller says:
"Our film comes out on April 30th. That is 9 months away - a really, really long time in the movie business. If they released the trailer now, it would surely be forgotten a few months from now, and then what? This amazing teaser would have not had the impact that it should."
This probably means we will not see a teaser in front of Rob Zombie's Halloween II as most have speculated. Perhaps it will be with one of the many horror films/sequels/reboots hitting theaters in October.
