10 years is reasonable if that means PSP2 comes out at year 6-8. And I think that is what they are hinting at. The PS3 connectivity will go a long way.
The GBA did the SP which was a quantum leap forward. The PSP could do something similar next. Make it like a slider or flip phone, better screen, longer battery etc.
A PSP2 could easily do only slightly upgraded graphics using a chip that is compatible with PS2 roms downloaded from the PSN store and backwards compatible with PSP games. It could have 8-16 gb internal flash memory. They don't need to push the graphics as the DS2 will probably be gamecube level at best.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
