Hi,
Adobe has stopped any improvement of Encore for because the use of physical medias is decreasing because everybody watch movies on iPad or iPhone..
This is a bad reason, or a crazy reason : the 4K movies and camcorders are now available and, as I know PP CC is able to work with this size.
It is crazy to watch 4K movies on an iPad connected to Cloud. The best is to watch from a physical media, so WE STILL NEED ENCORE and an ENCORE CC release.
As I know, 100 GB disks might be available.
