Well, if all 3 went bust that would mean there was no market anymore.
If two went out, obviously fans all go to the survivor.
If Nintendo went bust, fans would follow the franchises.
If MS went bust, most would go Sony (or at least they would have in the PS2 days).
If it were Sony... it depends. PS3 owners would almost certainly go MS. But there's still a legion of unclaimed PS2 owners out there. Clearly most are not part of the early adopter/tech-head crowd. And other than GTA, I'm not sure any franchise or genre dominated PS2 sales. So aside from 12m GTA fans, I'm not sure one can reliably predict where their fans would go. 360 has the tech and shooters, but Wii has the buzz.
