Another update on the Jurassic Park re-issue. This quote is from the Home Theater Forum:

=========================
I emailed Universal to see if the 2D disc is getting the new transfer as well and it's not good news i'm afraid.

This is what they said:

Thank you for contacting us.

The 2D Blu-ray and DVD releases to be included is our upcoming "Jurassic Park" 3D package will use the master that was created for the Jurassic Park Ultimate Trilogy in 2011.

We appreciate your interest and hope that you will continue to enjoy our releases.

SIncerely,

=========================

Based on this report, for those who want the remastered version, the 2D version (for those who want the movie in 2-D) will need to be obtained from the 3D Bluray. If playback on 2D gear is restricted, that will be able to be bypassed with certain software.
