I've read that they may be sticking the 1.6 4-cyl in it (same as Versa sedan / Note), which would give it better city numbers than the Versa (less weight), and slightly lower highway numbers (worse aero).
But I've also read that it may come with a 1.2L 3-cyl. If it does, it'll have slightly worse city numbers than the Mirage (Micra is apparently a few hundred pounds heavier), and slightly worse highway numbers (higher drag coefficient).
Update: it's the 1.6L only, see -

Pricing: they're hinting it will set a new benchmark for affordability. We'll know what that means next week.
