The Xbox 360 owns America, and most of the western world in terms of pure market share, game unit sales and profitability. The PS3, however, does extremely well on it's home turf of Japan where the Xbox 360 is basically ignored. In Japan, however, the biggest selling games are the ones that are not localised for Western markets until years after their launch.
In terms of most of the people on this forum, the Xbox 360 is the undisputed king of the hill in your markets. The PS4 only just claws ahead when you factor in the largest market on earth - Asia - and the fact that the Xbox 360 just failed outright there.
Halo 4 alone surpasses the lifetime sales of the entire Uncharted series, and made Microsoft more money than the top three Playstation exclusives combined. Sony aren't nearly as big as people think that they are.
In terms of raw financial success, however, Microsoft has left Sony for dead. Across the entire breadth of this generation, Microsoft managed to turn a profit from it's Xbox and Entertainment division, thanks mostly to Xbox Live. And that's after you factor in the Red Ring of Death fiasco -which cost over a billion dollars to remedy.
Sony, however, has actually lost money with the entire Playstation 3 debacle. Sony expected the Playstation 3 to sell like hotcakes, and it failed spectacularly right out of the gate. When compacted with the amount of money the Playstation Portable and Playstation Vita have lost Sony over their life, Playstation is the least successful name in gaming since the old Atari days. In fact, the loss is so great that the mismanagement of the Playstation brand in all it's forms is single handedly responsible for Sony's net losses for the last seven years.
What's humerous is, of course, Nintendo. They managed to make more money off of the original Nintendo DS alone to surpass the profits of the entire range of Xbox, Playstation 2, Xbox 360, Playstation 3, PSP, Playstation Vita and Xbox Live combined. Add the Wii into it, and Nintendo are literally laughing all the way to the bank. Even if the Wii U is ultimately a complete failure, they've got enough money in their coffers to fund their company without any profits for the next five decades.
