Any update on the Pi4?

Hi,
I have the Pi4B 8Gb and I was hoping to run OSMC and Kodi, with SMB shares. Obviously it’s not ready yet, which is somewhat frustrating.

What is this about releasing Buster first? I thought Buster was released, or is this because 64Bit buster is still in beta?

Will the new release include a 64Bit compatible version?

Cheers
