Well I don't know but I am in Europe too and electricity is very expensive here even in Eastern Europe countries like mine.
Mining is going nowhere at the moment, so I like everyone else replied am waiting for these newer chips, hopefully legit cloud mining like Eobot will incorporate them.
If your electricity price is high, you will not ROI even on the 16 nm miners unless you get the first batch and before the difficulty jump.
Those batches tend to be really expensive and the time between which you pay and receive the thing usually fuck you over. Its not necessarily the case, but look at people who paid 2k per S7. Ouch. The S7 value pretty much raised at the same rate otherwise earned in BTC, meaning whoever paid for electricity on them lost money.
The problem is, the nice new things goes to big centers first. By the time we little ones get some, they're already being rolled out on an industrial scale for a while, which mean we don't really get in the "easy time" before the diff rise.
One thing is we are in a unique time with having coming up. So getting in first batch could be a huge advantage. It's hard to say without knowing price and when talking about 16 NM we won't know price with all the NDA's chances are for a while.
Having is huge though as far as miners considering they earn 1/2 as much after having so there is a premium most would pay to get quick before having. How much premium? That is a good question.
