No, its still too early. Look for something to be posted near the end of April.
I know we all go through this each year though. JAMF typically doesn't announce the next JNUC dates until middle of Spring or thereabouts, and doesn't have a schedule of sessions available until much closer to the event time. However, most people want to know the dates and the sessions much earlier so they can make the case to their org for travel arrangements well in advance.
