Mitsubishi's website now has the 2018 Mirage info. When going to the "Build and Price" area, you can now only get the ES with the five-speed manual. Both SE and GT are CVT only.

This his hardly surprising. Nissan did the same thing with the Versa a couple years back. So did Kia. You want to row your own gears? You'll need to get the base model.
