According to "sources" that have contacted IGN, the eventual PSP 2 handheld will have dual thumbsticks, touch screen interface, the removal of UMD, and other hardware improvements.
Sony representatives have declined any comment on the rumor ("We can't comment on rumors or speculation,") but the increase in rumors has flared since CES.
The original PSP has been updated twice over its lifespan, but only with small hardware revisions, mainly making the system lighter and thinner.
