We have Antminer S5, C1 and Spondulios SP10,20,30 and so on.
Which ones will we have next year, and what are their specs going to be?

A lot of miners get sold and move into lower and lower electricity areas. As a example some machines eventually wont make sense for me to run since electricity. Eventually they will be sold. Someone with lower electricity price will run them. A example of this is me selling my dragon 1T. I'm sure it's somewhere still running. I just could not justify it with cooling during summer. I kept by far most of my machines.
One day they will be completely taken offline but I think miners stay online longer then a lot think. Especially with this summer's difficulty raising at a very slow pace. It's really been a great summer for those who mine.
