BTS to EOS June 2018.

Someone please elaborate on token upgrade. What to do with OPEN.EOS, GDEX.EOS, BRIDGE.EOS on all the Bitshares platforms. Apparently, Open Ledger says an automatic upgrade to new EOS will occur. Therefore, leave current EOS in Bts wallets, instead of transfer to an ETH wallet.

Can someone confirm, and whether its an EOS upgrade, and/or receiving a fork of extra new tokens.
Thank you.
