The price of bitcoin has halved 2-3 times since the ATH. In terms of mining profitability, effect of price halving and reward halving are just the same, since miners are paying bills in fiat. Therefore, a planned reward halving should not have a very dramatic effect on the hashing power (see what happened after the first halving in 2012). Also, price is expected to raise after halving due to decreased supply, which will compensate at least part of the loss of reward halving.
I have seen a proposal by an Israeli mathematician to change the way miners get their blocks from pools, that he claims willo reduce the risk of centralization by letting individual miners choose which transactions to include in a block. Perhaps.
There is that "21" company that apparently intends to put mining chips inside domestic equipment. Let's see...
Probably you are staying in the speculation forum for too long. We already have that for a long time. It is called "getblocktemplate", the BIP22 and 23. At least the Eligius pool supports GBT.

As a professor in computer science with academic interest in bitcoin only, I suggest you spend more time in the technical forum rather than the wall observer.
I as well as others have directed him to other more technically appropriate area's in the past to no avail.
