Don't get me wrong 4Runners are great and still very popular, but wasting the Land Cruiser name on what is, essentially, a new FJ Cruiser would just be stupid marketing. The Land Cruiser names does mean something even in NA. At the end of the day it is the product that is built that is more important than what they call it. But if Toyota wants a modern FJ40 to compete against Wranglers and Broncos just call it an FJ Cruiser for goodness sake.
BTW, Land Cruiser is happening. Toyota has confirmed it on social media.
