When will Sencha touch merge the data package with Ext JS 5?

In the release notes of Ext JS 5 it mentions that:

This package contains the core code that is shared between Ext JS 5 and the next major release of Sencha Touch

I guess you don't have a release date for that new Touch version, but could you give a very rough approximation? 1 year? a few weeks? a few months? It would be very helpful for us in order to plan our development for the incoming months.

Thanks
