So your saying you expect it to stop? I find little evidence that it will ever stop, the continual halfing every 4 years of mining rewards clearly points to a about ~20% deflation per year over the long term as the price of BTC must rise to keep mining profitable.
Not necessarily. Fees can rise, as well.
Once we get closer to market saturation, and have a better developed economy - by which I mean more goods and services valued directly in bitcoin - we'll see a lot smoother price movements.
