The NPD Group's Gaming Figures for June, Have Made the Rounds and Both Microsoft as well as Nintendo, Have Something to Crow about, Albeit for Very Different Reasons. Nintendo is the Most Eager to Prove itself and Says that, the 3DS has Hit 5 Million Total Sales in the US since it Reached Gamers' Hands in the Country. The Tally Doesn't Compete with the Heady Numbers Smartphone Designers are Used to but, it's a Milestone for a Handheld Console whose Prospects were Dim until a Sudden Price Cut Fueled Sales a Year Ago. Before Nintendo Lets the 155,000 3DS Units it Sold in June Get to its Head, however, it's Important to Get Context from Microsoft's own Achievements: Redmond Shipped 257,000 XBox 360 Units that Month and has Had the Lead among All US Consoles for the Past Year and a Half. We're in the Dark on Sony Data, although it's Important that just 90,000 Wii Units Traded Hands in the Same Month -- as Clear a Sign as any that the Wii U Can't Come Quickly Enough for Satoru Iwata and Company.
