I've said it before, but seriously, I can't fathom it. It's just dumbfounding. Nearly every single major franchise that sold the GBA to so many people in North America has been successfully translated to the DS, and in some cases with even better results. Castlevania. Advance Wars. Sonic. Kirby. Mario Kart (not a port). Mario & Luigi. Wario Ware. All of these have arguably better versions on the DS, and they were integral to the success of the GBA. Combine these with some awesome new IPs or new handheld iterations, and the DS's library is nothing if not healthy. The only two big franchises left are Pokemon and Metroid (both coming sooner or later). And please don't say anything about new "traditional" IPs - when Madden is annually on top of the North American charts, that clearly isn't the case.
So why on earth is the DS selling so badly over here? After the launch, I knew Kirby and Meteos wouldn't be enough to boost sales significantly. But I was confident that when autumn and Christmas came, the great new titles would push the DS on top once and for all in a big way. I mean, come on, that lineup from September to December was just brilliant. When this didn't happen, I was shocked, but I waited for Metroid Hunters; great graphics, online, FPS, handheld? Bingo! Or was it? We don't know the actual sales numbers, and NPD is inaccurate as usual, but all signs point to it horribly underperforming.
There are some bright spots though; namely the DS Lite, New Super Mario Bros, and to a lesser extent, Brain Training. If Peach sold so well (relatively), then NSMB should be a hit. But all bets are off now; from what we've seen, anything's possible. I will say, though, that I will give up on this market if Mario doesn't help the DS.
