Demand building for hybrid minivans

According to the linked article below, demand is building for hybrid minivans. OK, that's cool, and certainly it's technically feasible; Honda and Toyota both build their minivans on what's basically a midsize sedan platform, and thus could probably go down this path relatively easily. The real question revolves around the strength of the minivan market, since it "only" comprises about 1.5M annual units. That could change with rising fuel prices, of course, but the expanding crossover market might suck up many of those ex-SUV buyers and thus could prove to be a better place to launch a hybrid powertrain. Then again, maybe hybrid powertrains are exactly the sort of technology needed to wake up this market segment.
