While that might technically be true, although the PSP has a pretty poor attach ratio--IIRC it's around 2--the problem is the lack of support.  Third parties threw almost all of their core/hardcore games at the HD consoles, so the core gamers bought those; while putting spin-offs and "casual" games on the Wii, which the core audience ignored.  Nintendo put their best games on the Wii--obviously they won't support the competition--so Nintendo's core fans bought the Wii, which is why Nintendo continues to do well with their own hardware.

If third parties were to put more core games on the Wii, they could lure core gamers to the machine; but after putting so many core games on other platforms, they'd rather just keep supporting those.  Sucks, doesn't it?

Hello txrattlesnake. Another alt? =0

The PSP doesn't move any software in North America. I know Japan is different but no PSP titles charted in the NPD Top 30 for last month.

I do find this going back and forth pretty interesting. The Devs at Namco have decided that they did not want to port a game to the Wii. Usually the ultimate decision maker is money. Namco simply believes that the profit will not reach the company target ROI given the cost (different control scheme, different graphics, etc) and projected revenue (weak 3rd party sales). I seriously doubt that "hate of the Wii" had anything to due with this.  

But that wasn't thee excuse listed at all.   If it were, this thread would be half as long (still long but not this long).

Most of are simply debunking the given excuse.   That's all.  Nothing more, nothing less.
