No game-changing ASIC out yet? 
What do you mean. The existing mining setup already work well and if anything super efficient came out, it would take no time at all for it to become the norm and no game changing would really be done.
It always depend on what your electricity cost is. That wont change.
Some people tend to say comments like that. It has no basis, they always want the next best thing. Compare last gen to this gen... it's a pretty big difference on efficiency.
But yes you can look into future and say "It's going to be better then!" or something like that. And it's true, but it seems to me people who say like what hugs do are the type that just never buy new gear. They will always justify it with there will be better.
As a miner I always want some gear running. It would be a lot easier to sit on sideline and say it will be better next gen and let my coins set there doing nothing. But I choose to try to expand my amount coins.
