Uh...I think you need a deeper analysis first. What was competing against the DS? The PSP. We all know how that competition went. So for the portable market, the DS dominates. The Wii is selling quite well but so is its competition: PS3, 360, and even PC. It's pretty much the Wii against all three not to mention it still has to shake its image, whether the image is correct or not. From a publisher's perspective, they're going to put hardcore games on the PS3/360/PC. Unless that part of the gaming population dies from a plague started by a Nintendo fanboy, the Wii won't get that type of support as much as the DS.
Really, if you know a specific segment of gamers exist on one platform, you're going to make games that will cater to those gamers.
