My understanding is that the current size is the one which produces the most yield under the current process using the stepper. It's not the choice by the camera makers or sensor makers etc. I used to have a link which explains this, but lost it. Will dig it again. BTW, Canon developed a process which creates a larger sensor size by one step process (not having to repeat) which significantly reduced the cost of larger sensors. One step process or the multi-step ones, I forgot the detail. As I said, i will dig it out, or the resident expert (s) should complement this ;-).
