"By 2011 the PS3 will have caught up with the Wii."

Sales of the PS3, which have been sluggish, seem to have taken off after Sony removed some features and dropped the price. In Japan the PS3 even outsold the Wii in November, according to Enterbrain, a market-research firm. As more games become available for the PS3 next year, sales are expected to rise even further, says Mr Harding-Rolls, so that by 2011 the PS3 will have caught up with the Wii. In short, each of the consoles will be in front at various points in the “console cycle”.

Microsoft's Xbox 360, Sony's PS3 and Nintendo's Wii are fighting for supremacy. In September the Xbox 360, which was launched in late 2005, a year ahead of its two rivals, was overtaken by the Wii as the most popular of the present generation of consoles (see chart). Mr Bach says he is unfazed. “It's not even a statistic I track all that closely,” he says. The Wii's popularity stems from its low price and its innovative motion-sensitive controller, which can be pointed and waved to control the on-screen action and encourages novices to give gaming a try. But the Wii lacks the high-definition graphics of its two rivals, so it could soon start to look dated. The real battle is between the Xbox 360 and the PS3, Mr Bach suggests.
