I think people want a second analog on the next handheld, not on the newer version of the current system.
Personallly, the one stick thing smelt a lot like Sony wanted to differentiate the PSP as being something other than a weaker PS2 on a smaller screen. Instead of doing something better (like Nintendo with Touch screen vs motion controls) they instead opted to make it definitively weaker. That's the problem with the PSP (aside from piracy of course), it's a weaker PS2.
By not differentiating their handheld product from the home console brother enough, Sony found itself in a tough spot, especially with UMD not lighting the world on fire (and thus, the PSP is an illegal multimedia beast).
What sony needs to do with the PSP2 is, if it insists on making it the weaker version of the home console, at least do it right. Dual analog sticks is a start. Also, focus on something other than "best possible graphics on a handheld". Nintendo pushed art style, and that's why a lot of the best games on the system are not the most technically beautiful of the system.
A fresh start is what the PSP2 needs.
