The Theta-II crossovers were indeed rumored to be MCE'd for the 2014MY but it doesn't appear like that's going to happen. It might have been pushed back to 2015, or GM might have decided to cancel the project as a whole as the Equinox/Terrain are scheduled to move to the D2XX platform in the near future.
That move to D2XX will also bring about a slight size reduction so if you're liking how roomy the Theta-II models are you might want to think about picking one up.
