Okay, let's do some math. 77.2 million Xbox 360s sold worldwide. Even assuming a third of them are replacements or a household's second console, that still leaves 51.46 million users. That means Microsoft is pissing off a solid 2.57 million people. Just pause for a minute and think of how many of those people, knowing that whatever they get they won't be able to play their 360 games on it, will choose to buy a PS3 or Wii U instead. How much potential profit Is MS losing because of that? I can't say, but certainly enough not to ignore it.Only five percent of customers play previous-generation games on new gaming systems.
Now, I understand why they're doing it. Much like with the PS4, the Xbox One uses a vastly different architecture than its predecessor; x86 instead of PPC. And you know what? That's actually a decent reason. But to publicly make a statement that backwards compatibility is boneheaded? That just makes them look even worse than they already do this week. This kind of excessively defensive publicity is the last thing they need.
P.S. Thanks
