I think the cost per transaction will drop to more reasonable levels as the block reward drops.
You have a point there! I think you are right. Do you know on what a block reward depends?

The block reward started at 50 btc per block and is now at 25 btc per block. It divides itself by 2 every 210,000 blocks.
So when we hit 420,000 blocks we will be looking at 12.5 btc per block as the reward.
