Easy question, easy answer: When it's ready! And that depends on how many people are actively working on it. And that depends on, well, basically on how many people are interested in ARM and have enough spare time to work on it. That number isn't quite high.
There's plenty of hardware, but it's all crap. I say that without actually knowing all hardware. But I know, because my limited experience told me it's the same as in the 32-bit ecosystem. The raspberryPi 3 would be the first 64-bit platform we might support, running a 32-bit kernel. One could do the same for other harware, but most of them are China crapware and as soon as you wrote the first driver there will be a next generation of that chip and the old one is garbage. So far every Allwinner hardware feels the same. I have a PineA64. I ran it once with linux and then packed it back into the box. I did the same with the Qualcomm 410c, which seems a bit better though. I just found out I can run u-boot on it (instead of fastboot), which is a lot better than fastboot alone. What we need is stable hardware that has proper documentation and is properly upstreamed. That's a combination that isn't often found in the ARM ecosystem. Especially the PineA64 was completely rushed. I think the Dragonboard might actually be helpful to bootstrap OpenBSD on ARM64, but otherwise it's not really useful. The rPi3 can do that, too. I have my eyes on bigger, but more expensive, hardware. https://www.solid-run.com/marvell-armada-family/armada-8040-community-board/ http://b2b.gigabyte.com/products/product-page.aspx?pid=5864 http://b2b.gigabyte.com/products/product-page.aspx?pid=5928 http://softiron.co.uk/products/ At least those have chips that are supposed to be used in servers and not tablets.
