Oh man

I doubt Kanna and Hayato (because releasing Kanna without Hayato would make no sense) would come next summer. Mainly because that leaves no room for KMS's winter's update.

We'll probably get all the hyper skill updates in one shot to make up for the time. JMS will need to have Tempest be completed before we could get those classes. Let's say we finish the standard tempest cycle in mid-February. There would be plenty of time to get a single hyperskill update and then the JMS content before Summer, which would be when we would likely get the KMS winter content.
