It's still vaporware now, unlike alternatives. What's the fascination about 64-bit architecture anyway, apart from it being a bigger (=> better) number?
It's an easy benchmark for the common consumer to look at and feel they have selected the right product. They don't have to know about the differences between A35, A53, A57, and A72 much less why those models are better than the A7, A9, A15, A17 processors. They don't need to know that Android isn't 64-bit. They don't need to know that the 1-3GB of memory in their phone isn't going to benefit from 64 bits.
They do feel that no one is going to sell junk labeled as 64-bits, and I mean come on, why would the manufacturer display it's got 64-bits unless it was really important?
Is it actually? You loose almost all the conditional execution, lots of the interesting shifted addressing (I think Aarch64 allows shifts up to 3 only). You get more registers. Oh and no 16-bit instruction mode anymore.
