There has always been the intention of making the Mobile App version of the game as similar as possible to the Browser version.
In many cases, the mechanisms to do so can present a challenge. Some things cannot be incorporated exactly as they are on the Browser version into the Mobile App, so it requires 're-inventing', which then requires testing, refining, or even starting over.
The only time there is an Announcement, it's on Beta to let everyone know it is coming, and on live to let everyone know that it is either being tested or that it has been incorporated.
