Full blocks are not going to come early next year. They're here now. If a transaction fee market develops, good luck in EVER getting the 1MB limit raised. Miners will grow dependent on the extra revenue stream.
Yes, miners want more income through fees, but less transactions doesn't equal more income. You could have more transactions (more revenue) and less profit per transaction but in the end higher profit. Its a question of balance.
In other words the logic smaller blocks = higher mining profits doenst work. Otherwise you could choose a 50kb blocksize, but i am sure thats not what miners want.
