Unknown at this time. All I can say for certain is that the server tools will continue existing in some form, since they are required for administrating the server component (at least, they are currently). When/if they do away with the tools entirely, we will likely receive a notification well in advance that the administration process is changing.
Jamf no longer updates or distributes Recon, and it was removed from the software package in version 10.43. It looks like they're getting rid of their client apps, since they also announced that Jamf Admin has also been deprecated and is to be removed later this year.
