While it's always great to have more choice in the marketplace, I have no idea where Nissan is going as a company (at least in Canada - the Micra probably makes a lot more sense overseas). I can't imagine this vehicle will do anything except cannibalize sales from the Versa.
I'm sure the Nissan Canada execs are happy to have this vehicle - but they've already got a solid (though certainly not spectacular) small car lineup in Canada (Versa, Sentra, and throw in the Cube and Juke too). I bet they'd be a hell of a lot happier getting a new/refreshed Titan, Frontier, Xterra, Armada...vehicles with actual profit margins, that used to sell in decent numbers in Canada - nearly a decade ago, when they were actually class competitive!
