Please let us know what information/help are you looking for.
I'm looking for when the next version is coming out. Or at least something that will work with vsphere 6.5.
From the lack of response is it safe to assume that VMware studio as a product is dead and no further development is being done to add support of modern operating systems and VM hardware levels.
I courtesy response would be appreciated together with a pointer in the right direction regarding vApp creation for vCloud Director
