PSP2 doesn't exist so I don't know how it entered the discussion.
Anyways it's hard for me to assess the graphical capabilities of the 3DS because the visuals vary wildly from the games presented. I'm not entirely convinced that some of the higher end screens aren't bullshots. Kid Icarus si the only one I'm safe saying is at least representative of what the 3DS can do as it was built from the ground up, and it looks great. If everything here is real then 3DS is far beyond PSP in visuals.
yes 3DS is powerfull but the PSP2 discussion came up because some people were caliming it to be PS360 graphics but they aren't that good
they are as good as PSP,WII,PS2 things.they can look even better as it is on a small screen and as the gen progresses the graphics will progress but still no way near PS360
also IWATA said that because it was 6 years since DS release they gave it a graphical upgrade but the upgrade only made it look like what was already their on a rival handheld and last gen home consoles so they didn't really do an upgrade
and so the PSP2 will have better graphics thing came up
