Minivans are not dead. Pretty much every model still tops 100,000+ sales per year. (Mazda 5 being an exception, though it is really a subcompact with sliding doors, not really a minivan)
2013 model year sales ranked by top sellers:
#31 - Honda Odyssey
#34 - Dodge Grand Caravan

My reality is that they only sell $45,000 suvs or much cheaper minivans that can fit my whole family... So for me, they are here to stay. My minivan seats 8, a suburban seats 8. Most suvs seat 5...
