I'm just surprised they found a company willing to associate themselves with the SimCity brand given the past month of turmoil. Presumably there was already a contract in-place for this deal - but still, you've got a bunch of pissed off fans for a game that still sits with a massive 1-star rating on Amazon, and that's scheduled to have a new wave of Mac users come on-board putting additional stress on their infrastructure. Plus how many people are going to rush out and buy a Leaf because they saw it in SimCity?
A month, when the Nissan deal has probably been in the works (at least) for a year and will go on for years (unless EA claws back IAPs at some point). To them the "turmoil" is a momentary bit of nerd rage leading to some copy.
