That's a common misconception, but the ones who matter to decide which will be the dominant fork are the so-called "economic nodes", not miners. Nowadays, the most important "economic nodes" seem to be the exchanges (after all, Bitcoin is useless unless you can convert it to something else, be it goods, services, or fiat money, and the later seems to be its most important use nowadays).
