2018. Microsoft released Exchange 2019, but no way to deploy it

Microsoft has released a new version of its e-mail and collaboration server Exchange 2019. And companies can already download the update, but there is one problem - there is no way to install it. Because it works only on the server operating system Windows Server 2019 which hasn't been released yet. As for the innovations in Exchange 2019, they mainly improve system performance. The new version can use up to 48 processor cores and 256GB of RAM and is optimized for SSD-drives. In general, it is obvious (and the company does not hide this) that Microsoft is developing Exchange with a focus only on large and very large companies. And they want to transfer all small and medium businesses to the cloud-based Microsoft Office 365, which provides the email server as a service.
