Believe most expert opinions out there points to a few observable trends and predictions:
1) Mining operations will fall after the halvening (some reports has indicated around 30% has already shuttered - especially those on older antminers)
2) For mining operations to continue, the price needs to be stable at above US$10,000, or thereabouts, depending on other factors below
3) Mining operations using newer equipment (that has lower wattage use and a larger hashing rate) would be able to make a profit (albeit smaller now)
4) Mining operators would be forced to join resources to spread out liabilities and risks (Especially when it heads towards subsequent halvening)
5) Mining operators in countries with low electricity cost, high security, and minimal government intervention will survive
6) Probably only if technology progresses quickly enough would there be opportunity for mining operations to thrive
7) Government subsidies (if any) also poses an avenue for mining operations to survive

In the future (not too far from now), when all the bitcoins are mined, all operations will seize/close down except for the largest mining pool to process transactions (by then, with the monopoly in place, transaction fees will be high)
The good news is, as we continue to mine, the BTC prices will fluctuate less, and the rarity factor will soon make the price rise due to demand and hopefully attain its full market capitalization potential.
