There's been talk on the Aiden announcement thread that an adjustment to block reward should be implemented:
https://bitcointalk.org/index.php?topic=558414.msg6250887#msg6250887The best recommendation came from buttonmc which is quoted below. Two poll options:
-Don't change anything! --> this means don't change anything.
-Change halving schedule! --> change block reward / halving schedule as outlined by buttonmc
Vote!!
This is still not enough infrastructure to outweigh the rate of current mining.
I agree with a faster reward halving, but it needs to be done more thoughtfully.
This is the current distribution:

At 210,000 block reward halving you run into a convergence on 21 M coins, not the desired 84 M:

I think the optimum coin release schedule involves a combination of variable block reward halving times along with a minimum block reward of 3.125:
blocks reward coins total coins time (years)
210000 50 10500000 10500000 0.199771689
420000 25 10500000 21000000 0.599315068
840000 12.5 10500000 31500000 1.398401826
1680000 6.25 10500000 42000000 2.996575342
3360000 3.125 10500000 52500000 6.192922374
10080000 3.125 31500000 84000000 15.78196347
The original distribution period was 8 years, this method increases that time period to 15 years. However, you can see that it bottlenecks the coin distribution to 42M coins in 3 years rather than the original plan of less than 1 year.
