Yes, it is planned and will be implemented. It is highly demanded feature: was already several times/requested here on forum, with reference to Sublime implementation.
Planned for next major release, but maybe will be added in one of the 1.5x versions.
Generally I like the way it is done in ST2, except of selection method - Ctrl + Select, while it conflicts with word selection feature (Ctrl + Click on text selects current word and movement pressed does word range selection).
