You may have a good point. But I don't think it's feasible to buy a Atmega2560 and then build a custom pcb. Majority would rather buy an Arduino Mega for their project and be done with it rather than building a custom board. My previous comment tries to convey that you need to leave the Arduino in the project instead of just using it as a prototyping platform once you go SMD. Well sure, that'd increase sales for arduino boards.
