The VW e-Golf and BMW i3 are no less cars than the Leaf is. The e-Golf in particular competes directly with the Leaf, offering similar features and price. The i3 is pretty pricy, but it is a BMW after all.
I agree with you about the e-Golf. I had previously seen numbers like this: http://insideevs.com/monthly-plug-in-sales-scorecard/ that make the e-golf look like they were converting a few hundred cars to electric drivetrains as a test, but I didn't realize that the car was selling in meaningful numbers in Europe. I would love to know if they are making a profit on them or plan to in the near future. You might be right about the i3 as well, but everything about it screams "concept car" in my mind. I also consider the Volt to be a serious attempt to win the market, but it's not a fully electric vehicle.
