So it is looking like the old script for the next Star Trek movie is being thrown out because it wasn't working, if there is a complete rewrite I wonder if Shatner will still be doing a cameo.

It seems to me that if Paramount ever wants these movies to become really big they need to let the new cast stand on their own and not keep reminding people that they are younger replacements for other actors they love by having the older actors pop up all the time. TNG didn't become big by having a TOS cameo in every episode, maybe movie three with a new director and writer would be a good point to start letting the new cast stand on their own and blaze their own trail. Then again with the movie set to come out in 2016 a Shatner cameo may not be something the studio wants to pass up. It will be interesting to see what Paramount decides to do at this point.
