I he have to pray for that the upgrade for 2.3/2.4 don't take so long that the 2.2.x are so discontinued that he can't update our modules, because don't support (or fully support) on this discontinued serie.
I think that the priority it had to 2.0.X and 2.2.X become only one, in 2.3 version of xoops, and not speed time in implement new funcionalities in this version(other that the necessary for the union of 2.0 and 2.2 series).
And next step are to implement the new functionalities, and support for the new version of php/mysql/apache, and the new theme support, and other stuff for the 2.4/3.0.
And not everything at same time, nor to implement the new functionalities first.
