Got the new Sony Android TV, mostly because I expected to find a Playstation Now app on it. However, no such app exists currently. Can anyone tell me is there any way to install the Playstation app on it, if not, when can I expect for it to become available.

I've tried updating the Bravia TV apss and the System OS, but it states it is up to date already. The tv is runing on the PKG3.533.0108EUB version of the OS software. 

In addition, noticed that some older versions of the Sony Android TV have te HBO Go app, but not the current newer model. When can I expect to have this app available as well?
