Here in the U.S., Michael Dennis from the NGS explained at the TRB AFB80 summer meeting with the 2022 adjustment being planned the basis for state plane coordinates is going to change. Right now the NGS has a proposal that is open for comment by anyone on the relative benefits of their proposed changes.
Here is the NGS information.
2022 SPCS Policy Changes
An update of the State Plane Coordinate System (SPCS) is part of the transition from the North American Datum of 1983 (NAD 83) to the 2022 Terrestrial Reference Frames. To this end, NGS will establish the State Plane Coordinate System of 2022 (SPCS2022), which will replace SPCS 83, the version referenced to NAD 83.
A Federal Register Notice (FRN) was published on April 12, 2018, announcing that draft SPCS2022 policy and procedures are available for public comment. It also asks for input on “special purpose” SPCS2022 zones. The FRN, policy, and procedures documents are available at the following links:

DRAFT SPCS2022 Procedures (PDF, 473 KB)
After reading the FRN and reviewing the draft documents, send your feedback to NGS.Feedback@noaa.gov. Comments may be provided until August 31, 2018.
Note that the draft procedures document includes contact information and instructions for requesting and proposing zones, as part of developing SPCS2022. Because that process may change based on public comments, such requests and proposals should not be submitted to NGS until after the SPCS2022 policy and procedures are finalized.
This change to state plane coordinates is going to have a major impact on the geomatics industry. Starting to prepare now is not too soon.
