And your point has no merit to it. You're relying on a premium priced version of a competitor's device as your proof of concept, when again, that's only the premium priced version and wasn't at price parity until about a week ago.
Also, you can cut Monster Hunter off your list for anywhere but Japan, and Animal Crossing, Luigi's Mansion, and Fire Emblem completely. Those don't sell consoles regardless of price. They're cumulative push titles where eventually there are enough quality titles to make the product appealing, but none of them sell the handheld to a very wide net of consumers on their own.
Mario and Pokemon do that, and pretty much regardless of price.
Another point I already made but you clearly missed: the games you cited are, with only one exception, Nintendo IPs that Nintendo has been producing titles with for several hardware generations now. Of course Sony's hardware would sell better if they owned Mario. It'd sell better if they owned Halo too. It would have sold tangibly worse if they didn't put Uncharted on it at launch for that matter. Sony doesn't own a handheld juggernaut IP, they can't make one over night. They have a strong software library but no breakout hits and you can't just design a game to be a breakout hit.
It's doing worse than it's predecessor, by a tangible amount. At this point it's going to end up closer to the PSP than the NDS in sales I'd imagine, so people will care about it just as much as the previous Sony handheld. Just more than the new one. I wonder why we'd see regression across the entire sector....
