Might be true. Might not be true. Might be partly true or completely false. It will probably be true but you can't be sure. They might select a target device or join up with a vendor and release a dual boot, might find a buissness model that support it...and/or just release a down loadable rom. Please read below...

"Sailfish OS downloadable to existing Android devices

Sailfish OS has been developed to be compatible with commonly available Android hardware platforms. Due to this advanced technology, Jolla is introducing the Sailfish OS experience as downloadable software to devices running Android OS. Users can soon start to enjoy the modern, gesture based Sailfish OS in selected Android devices and also renew the lifecycle of their existing older Android devices.

The Sailfish community has already ported Sailfish OS into several devices including major versions of popular Samsung Galaxy, Google Nexus, and Sony Xperia. Also, porting for highly popular Chinese Xiaomi products is under work in community projects.

In addition, Jolla is releasing its own Sailfish user interface launcher as an Android application, which can be used to simulate the Sailfish OS experience on Android devices. The app will be available for download in the near future from Jolla.com and from common Android market places.

“We see this as a huge volume opportunity for Sailfish OS as there are close to a billion Android users globally. Many of them are looking for new user experiences to freshen up their existing devices. Last year in China alone, about 100 million devices were re-flashed after the purchase with a new operating system. This approach allows Sailfish OS to scale into volume fast without limitations. This is a scaling opportunity in a similar way as we have seen in the mobile gaming industry recently,” Antti Saarnio, Chairman of the Board of Jolla comments.

Jolla will release the downloadable Sailfish OS software in phases during the first half of 2014. First, the UI launcher application is released so users can start to experience the Sailfish user interface in their existing devices running Android OS. Later Android smartphone users can get the full Sailfish OS to their devices."
