Xbox 360 sales in Europe have "more than doubled" since the latest price cut, according to Microsoft.
The mid-March move brought the price of the Core Xbox 360 to GBP 159.99, the Premium to 199.99 and the Elite to GBP 259.99.
Despite the assertion, Microsoft presented no hard new sales data.
The company also said the console's attach rate is seven per console, besting the PS3's 3.8 and the Wii's 3.5 per unit numbers.
"Xbox 360 is truly the next-generation console of choice among consumers, and today's numbers are proof that we are delivering on our commitment to achieve critical mass in Europe," said Chris Lewis, Vice President of Microsoft Interactive Entertainment Business in Europe.
"The highly competitive ERP, coupled with entertainment content that's appealing to everyone in the home, makes Xbox 360 the ultimate high-definition entertainment choice, and it's clear that we're already seeing this resonate with consumers."
