The difficulty level isn't neasescrily increased for every period. If a bunch of people leave the mining population, the difficulty level will be adjusted downwards to keep the Bitcoin block generation rate at one block every 10 minutes.This would happen if the market price of Bitcoins drops below what would be profitable at a given difficulty level. This would also happen when the payout per block drops from 50 to 25 (which will happen at block 210001).
