What quality are people seeing in the NGP that means that it will be any different to the PSP for Western consumer demand that will equate to third party support?
The main reason is because it is easy to develop for, due to NGP using simple components that are similar to most mobiles and tablets such as the iPad. It is also easy to port and using existing engines and assets, so if a developers is used to developing for mobiles, 360, PC and etc, then NGP will be a walk in the park to make games for. Hell there are already plenty of engines being announced for NGP, which includes popular ones like Unreal engine.
As for what makes NGP different to PSP, well Sony has corrected many mistakes of the original PSP.
Cartridges instead of UMDs - no shitty load times which many people hated
Touchscreen support - touchscreen has been a vital feature in the handheld market for the past 5 years, PSP missed a big feature here luckily NGP has this
Dual Analogs - this was a huge complaint for original PSP, now3 we can have controls exactly like console games without the controls being gimped
Competition isn't as cheap - 3DS isn't cheap, it may be cheaper than NGP but the difference won't be as huge as when DS was $130
Other controls - touch, camera, mic, gyro and etc, these things are what differentiate handhelds to consoles, now we can have games like Nintendogs and Brain Age due to extra controls
