It's the same logic as to why the ipad2 was able to cost the same amount as the first ipad2 did in its heyday, despite being statistically superior in every way.
Advancements in technology and production may in the future allow the same product to be manufactured at a lower price, which by extension implies that you can also make a better ipad for the same price.
