From a personal view, I've spent a lot less time in strategy games due to time constraints (also less forum time).
Also many have mentioned about the consoles, RTS just doesn't blend well with controllers.

However, in the wake (or dead) of things, more turn-based strategy games have popped up. Many games now have "tactics" added as suffix and made into TBS e.g. Arma Tactics.
TBS work quite well with controllers and touch screens since the user only controls one object at a time through a grid layout.
