I can only assume that you found this featured NetBackup post:

If we look at the diagram and process flow, it seems to me (NB: personal opinion) that only an Enterprise backup product can provide the necessary support for 'BigData' such as Hadoop and Nutanix.
We also see the 'backup host' must be Linux. There is probably a very valid reason for this.
About future support for BE -
I have never seen Veritas Employees sharing roadmap info in a public forum.
Best to reach out to Product Management via your local Veritas office.
