No overlap with the CR-V and HR-V?
Pricing will be the most important thing. They will have a line up similar to Mazda. Mazda2 (subcompact hatch), Mazda3 (compact in sedan and hatch), upcoming CX-3 (subcompact CUV based on Mazda2), and the CX-5 (CUV).
Now they should be able to match Mazda3, as Mazda had to come close to matching the Honda Civic when the 3 was built in Japan..
