Is the ZFS 100% sure will be in Ubuntu 16.04LTS?

Question

Some people on reddit say that it may not be in 16.04, will it?

I have lost lots of data on XFS, so I am looking foward to the ZFS.

It is a filesystem for containers (LXC, LinuX Containers) so not for the operating system itself. "ext4" will be the filesystem for Ubuntu at least for the next few years.

I can not pick it in gParted (well at least not yet):
