I disagree that a 4-cylinder is a bad idea for a minivan, it is exactly what millions of people want, but to accomplish this Nissan needed to seriously cut weight off of the Quest, starting by reducing the dimensions and overall size of the vehicle. Like I said in my previous post, if they would've gone with a smart efficient design positioned right between the small Mazda 5 and oversized Sienna, Caravan, they would've had a winner, I'm sure of it. Myself and my friends are all 30-something with 2 to 3 kids, and this is what we all want and need, an affordable people mover, not just affordable purchase price but affordable to fuel and maintain. I'm not a demographic expert but from personal experience I'm sure there are millions in NA who need this too.
The mid-sized van would be small enough to grab market share from small Mazda 5 minvan AND from the larger vans because it would be sized "just right", allowing for an efficient 4-cylinder and still accomodating 7 passengers and gear. It's about optimizing the size, and more specifically power to weight ratio to allow for an effective 4-cylinder.
I dunno...I don't disagree with your point at all. But it goes back to what I said earlier in this thread about there being so many more options for people looking for cars with the space of a minivan in something that's not a truck. I think if I were an automaker I'd rather build a small 3-row crossover rather than a Mazda 5-class Minivan. Despite having 3 rows of seats, the 5 only seats one more passenger than the Rogue. And the interesting thing is that due to the seating arrangement, the Rogue actually seats more and holds more cargo simultaneously. If you want to seat 5 people in the 5, you need all 3 rows, which leaves you with no cargo space (the third row is only a few inches from the liftgate). Fold down the third row in the 5, and you get 30% more cargo space than the Rogue, but you can only seat 4 passsengers. So the Rogue ends up being the more versatile car (arguably, I guess).
If I were Nissan and I wanted a slice of the 5's pie, Id consider a stretched Rogue with another row of seats. With a straighter liftgate and maybe 3 or 4 inches of stretch, you could have a third row on par with the Mazda 5, but end up with seating for 7 vs 6. Call it the Rogue Touring.

I have the QR2.5 in my Rogue and other than valve train noise in extreme cold it is a fabulous engine, lots of low end torque for a 4-cylinder and amazing efficiency. Now that's my impression of the QR in my 3100 lb Rogue, slap this into a 4500 lb van and I'm sure it would be terrible.
Today's QR isn't as bad as the earlier iterations (and a lot has changed, admittedly) but it still isn't on par with modern engines from other automakers. Even the Americans are making smoother more reliable fours right now. But early models had major reliability problems, including severe oil consumption issues and a habit of ingesting throttlebody screws and self-destructing. It left a bad taste in a lot of mouths and despite those issues being resolved, it still isn't the most refined four on the road. The KA wasn't silky smooth either (and sounded like a wet fart) but at least it was rock-solid and easy to maintain.
I also think the MR and HR are both superior engines technology- and refinement-wise. So, despite my usual preference of normally aspirated engines over forced induction, I'd like to see Nissan replacing the QR25 with an MR20DDT or even an MR20VDT. I think that would be particularly well-suited to smaller, lighter vehicles (including my imaginary Rogue Touring, or your proposed smaller Nissan minivan) and would also be popular with younger buyers in a base-model Altima and Sentra SE-R.
But, as far as the big new Quest goes, I don't think ANY Nissan four is a good option. The sideways VQ (the rear-drive VQ has evolved on a very different path from the front-drive variant) is so good at producing low-end torque that it's just foolish to look anywhere else for power in a car weighing in at much more than 3000lb.
