So what happens to the blockchain when POW ends soon? There are no Prime Controllers or Orion nodes to control the network and record transactions. They are supposed to handle transactions and mint coins when needed. If there are no miners and these parts of the infrastructure are not online the blockchain will stop growing and transactions and trades will become impossible to perform.
Actually according to the timeline, the prime controllers were already created on Monday the 15th. So they are already out there.

However, nothing in our wallets interact with them in any way. So, yeah, issue.
