Wii U launch-month revenues in US surpassed the Wii's by 21 per cent, according to NPD analyst Liam Callahan.
"The much anticipated launch of the new Wii U console brought in more dollars than the Wii launch in November 2006, up 21 percent from that launch month," said Callahan.
The increase is in part due to the Wii U's higher price point compared to Wii. Nintendo claimed 400,000 Wii U units sold during the system's first week of availability in the US. By comparison, in 2006 Nintendo reported 600,000 sales of Wii during its first eight days of sale in the US.
Comparing both launch performances, Nintendo stated that Wii U's unit sales were lower than the Wii's, but not significantly.
"Following its launch on Nov 18 and with only seven days of sales captured in the data, Wii U sold more than 425,000 units, nearly matching the Wii system's first-week total of 475,000," said the platform holder.
Callahan cites this as encouraging signs for overall consumer attitudes.
"With an average price 35 percent higher for the Wii U at launch compared to the Wii, this is an example of how consumers are willing to come out and spend when they see the value of the product," he said.
Despite overall retail video game decline of 11 percent year-on-year for November, Nintendo's console business faired well thanks in part to its new console.
"Comparing Wii sales from November 2011 to Wii sales combined with Wii U sales in November 2012, dollar sales increased by 76 percent," noted Callahan.
