Could anyone shed a bit of a light as to when the new E3 would be implemented.

NEW E-3 VISA FOR AUSTRALIANS
Section 5 of the Real ID Act of 2005 has created a new visa classification known as E-3 for Australians by adding a new Section, being 101 (a) (15) (E) (iii) to the U. S. Immigration and Nationality Act.

The new E-3 Visa allows nationals of the Commonwealth of Australia to enter the U.S.A. to perform services in a “Specialty Occupation.”
