Wow I'd actually forgotten about the possibility of a fourth contender. If a successful company like Apple were to enter the fight, they'd upset the whole order. I still say Nintendo isn't slated to win. They built their base on top of a bunch of fickle and impulsive casual gamers. If Apple were to offer a versatile, motion controlled home console for a reasonable price (huge if) in say, 2011 (a full year before anyone else) and relentlessly advertise it (like they do for their i-pods,touches and phones) that mound of part-time gamers would flock to the iGame or whatever its called in a second.
