After Windows 2016 is released, same as normal, the old licensing will not be available and you will be required to purchase your 2016 licensing under the Per Core model. However you will still have downgrade rights to use previous versions. However your licensing will be based at Per Core level even if you install 2012 (you can downgrade the version, not the usage rights).
If you are under an Enterprise scheme, these changes will not be applied until you renew your SA and will continue to purchase under the 2Proc Per Licese model until then end of your contract. Then you move into the tranistion process (same as SQL) where you report any devices that have more Cores than granted for free, and you will be allowed to have "free" licenses (which you will then need to pay SA for.)
If you have high core value boxes this will cost you more money. However it is totally dependant on the technology you have so you should work with your supplier when your transition is due to make sure you get the right conversion rate. Its quite a high conversion rate so a high % of servers will be "over" core licensed or match it.
Worth noting: On release the MLS "should" automatically convert all your Per Proc /SA licensing into Per Core /SA licensing as it doesn't understand licensing terms like this. You will still be under the EA original terms until renewal. If you are granted free licenses for additional Cores they will also never show on your MLS, so any tranistion work you do should be kept very very safe as its your proof of license.
