Research firm IHS iSuppli estimates that by the end of the year, people will have snapped up 3.5 million Wii U consoles worldwide, compared with 3.1 million Wii units in the same period through the end of 2006.
After the Wii went on sale, shortages persisted for months. Stores were met with long lines of shoppers trying to get their hands on a Wii as late as July 2007, more than seven months after the system's launch.
Though supply constraints are expected this time around, Fils-Aime says Nintendo will have more hardware available in the Americas than it had for the Wii's initial months on the market. The company says it will also replenish retailers more frequently than it did six years ago.
An initial sell-out doesn't mean the Wii U will be successful over the long term, IHS notes, citing its estimate that the Wii U won't match the Wii's sales over time.
Bajarin believes it's going to take "a little bit of time" for the Wii U's dual-screen gaming concept to sink in with people. If it proves popular, Nintendo could see even more competition at its hands.
"Technologically, it's not a leap of the imagination to see Apple, Google, Microsoft do something like this," he says.
