Back in January 2010, Paramount Pictures set a June 29, 2012 release date for the highly-anticipated sci-fi sequel Star Trek 2. Nearly a year and a half later, the screenplay is still not completed, which has many doubting that the sequel will be able to hit this projected summer 2012 release date.

Director J.J. Abrams has now expressed doubt about making the release himself, indicating they are more concerned with turning out a quality sequel than hitting the right date. Here's what he had to say below.

"I really don't know, we will see. We are working really hard to try and get that movie made as soon as possible, but we don't want to rush anything. The worst thing we could possibly do would be to put something into production to make a release date instead of a great movie."

He also said he's excited to get back to work on Star Trek 2, although the release date isn't the only thing he is unsure of. As of now, it seems J.J. Abrams won't make Star Trek 2 in 3D.

"I'm not yet considering it, but you know, I haven't gotten any phone call from people in suits. I know what's good for me."

We reported last month that screenwriters Roberto Orci and Alex Kurtzman are currently working on the Star Trek 2 script from a 70-page outline. Here's what J.J. Abrams had to say about getting back to work with the writers.

"The writers are hard at work on it, and I am excited about getting back to it. We are taking our time, though, because I really do want make sure we do something that is worthy of the first one."

Currently, Star Trek 2 will be released on June 29, 2012, although, if that changes, we'll be sure to keep you posted.
