The Sony FZ100 was the first mirrorless battery for cameras to make replacing DSLR cameras a reality and now it sounds like it will be replaced with a more powerful battery soon. It is unclear if this battery will be the same form factor as the FZ100, but if it is current FZ100 camera owners will get a nice upgrade soon. Third parties have offered additional power for years, but not enough to be noticeable.
Update: The form factor is the same so it will be compatible
