There was a time when the MBA commanded a higher price than Apple's other larger laptops. This was contrary to your argument (and what I meant when I suggested that 'Apple could make the MBA special...again').
I was in these same forums then and I remember several posts being critical of people who favored the MBA. To paraphrase,"They are getting so much less computer and paying more more money just so it could be a little thinner and maybe a pound lighter!" This was said as if people who paid the additional costs and made the performance sacrifice were idiots.
I am an electrical engineer and I work in an industry where smaller size wins (contracts). There is no doubt in the electronics world that smaller sized components often demands a higher price tag. For example, one can always choose to go with 'chip-scale' packaging where the silicon plastic packaging is replaced with circuits not much bigger than the silicon die itself (more expensive to make the chips and to place them on the PC board). This is just one example where you can pay more to make things smaller. They may have other options that can make it smaller for a higher price that are available. We have no clue what Apple could do if they spent the extra cash.
It was a long time ago when you had to pay a premium for a MBA and maybe Apple won't go there again. I just don't think you can make blanket statements thinking that smaller MBA will automatically mean it will be their cheapest computer.
It very well may turn out to be that the new 12" MBA is an entry level machine as you suggest (and I am setting myself up to be disappointed) but, at this point, we really don't know.
I remember when Apple released the very first MacBook Air, and it was not so long ago. It was in early 2008, and it was indeed very expensive. The Air only became cheaper in 2010.
I understand that smaller components are more expensive. But that does not mean that people in general will understand that. As you mentioned, people were complaining when Apple first released the Air, that it meant paying more for a lesser computer. People understand "big" and "small", and understand differences in products categories. Look at Apple product line and you will see that Apple tends to replicate what is in people's minds.
The cheapest product in Apple's line-up is the iPod shuffle, which is also the smaller. And the most expensive products are the largest Apple laptop (the 15-inch retina MacBook Pro) and the largest Apple desktop (the 27-inch iMac). People understand that a laptop may be more expensive than a desktop, but somehow fail to understand that a small laptop may be more expensive than a large laptop. It's weird, and Apple plays with that.
So, look at what we already have as a rumor. The rumored screen is a 12-inch with a 2304x1440 resolution. It is smaller, but the pixel density is the same then the screen in the 13-inch retina MacBook Pro. That means that the 12-inch screen in the next Air will be cheaper to manufacture than the 13-inch screen in the Pro. Smaller is more expensive, but when it has the same functionality. The processor in the 12-inch Air will be slower than the processors in the higher-end laptops.
