Contemplating? They are only discussing how much, they will reduce rewards, 10% of the blocks that reward will be gone, with a lot of work probably discarded in the process, plus a reduction.

I'm guessing based on the range they are discussing, the block reward will be about 50% of what they are today.... and it doesn't apear they will level out the drop, allowing the iceage to creep up while they keep farting around with the PoS code.

Let's assume for a second that a large number of miners will jump off making the rewards somewhat easier to get, they'll create a faux iceage on other algorithms/coins as they chase profits.

A lot of people will be very unhappy.
