Nerval's Lobster writes: Now that Microsoft and Sony have unveiled their respective next-generation gaming consoles, the two companies have cheerfully resorted to firing broadsides at each other. Whether the current brouhaha has any effect on sales of the Xbox One and the PlayStation 4 (if hardcore gamers keep complaining, they may even convince Microsoft to knock $100 off the new Xbox and bring its pricing down to the PS4’s level), it’s also drowning out what many perceive as the real issue: gaming consoles face an existential threat from mobile devices, most notably those running Apple’s iOS (with some threat from Google Android). First, there are signs that the hardcore gamer market is soft: console sales in the United States dropped 21 percent in 2012, and sales of new video-game cartridges haven’t fared much better. Second, PC/console games such as X-Com have begun appearing on iOS; if that trend continues, the console companies will have more rivals to fight against. Third, Apple is developing a game controller for iOS which could make it an even more dedicated opponent — and convince other tech companies to follow in its footsteps. But don't tell any of that to Microsoft and Sony, which seem content to fire at each other.
