It's 2018 and Apple has changed, and market has changed. If something was an unrealistic expectation, that was.
Actually, they could have the entry level with an dual core 2.3 (or something similar form the 8th generation), like it is in the 2017 iMacs and the entry level Macbook Pro. For the price of 499-599 $.
Anyway, it doesn't really matter.
For these who want, will buy it anway, for these who won't, they simply won't.
