The managing director of equity research at Wedbush Securities said the 3D-enabled device will appeal to all handheld owners.
"The 3DS will be a massive success. I think that the device is appealing to anyone who ever owned a handheld, including adults who owned Game Boy 15 years ago," he told DS.
"I expect the 3DS to be supply constrained for at least a year, and expect sell-outs through holiday 2011 and into 2012."
He said that Nintendo will "definitely gain a lot" from the device, such as a boost to handheld software sales, but added that it won't impact its console strategy.
The 3DS will be available in the early 2011 worldwide.
