Totally agree with your assessment NSR. Those who buy minivan, electric or not, are totally different driver than those who would consider the Model X. Model X driver probably care more for performance than those who buy an Odyssey. If Honda do what you said and create a $50k EV Odyssey, it might sell pretty well. If they use a smaller motor (don’t need to go so fast, 0-60 in 7 seconds should be sufficient), then a 150kWh battery might get you much further than 400 miles.
Nissan Leaf is a prime example. It uses a 24kWh battery, yet it can get 138 miles on it. So, with the 85kWh battery like the Model S, it would be able to get 488 miles. It does 0-60 in 9.9 seconds though, instead of the 4.4 seconds the Model S does. But some people might prefer range over performance.
Also, the biggest problem that need to be resolved is battery life. Right now, a battery will only hold 70% of the charge after 5-6 years and only 50% of the charge after 10 years. So, for those of us who keep our cars for a very long time (my current car is 9 years old), that would be a huge problem. I think that will drastically affect resale as well.
