The trend follows the Xbox's announcement of its three console variants, the Arcade, Premium and the Elite, dropping their prices down to $299, $399, and $499. Experts see this as a very favorable response, considering the price cut was announced only a week before.
"Xbox 360 is up 35-40 percent - that's from Friday, when the price cut came into effect, up to midnight Saturday," XBoxer quoted Dorian Bloch, head of the U.K.'s chart producer Chart-Track.
Dorian said the Xbox 360 will now have to continue the trend until Easter in order to reposition itself as a worthy competition in the war of the consoles, where it is pitted against the Sony PlayStation 3, which has outsold the Xbox for two consecutive months, and the Nintendo Wii, which is the console to beat.
Keeping ahead of the PS3, however, comes with the imminent challenge, according to GamesIndustry, in the form of Gran Turismo 5: Prologue, set to come out for console.
The game's hype has reportedly led to a million pre-orders, and upon the prediction of analysts, a boost in PS3 sales.
