Despite being culprit to cramped fingers, Sony has no intention of redesigning the PSP. Sony officials refuted the idea that that PSP was in need of a DS Lite-style remake, stating that the system will see no physical alterations. The design will stay the same, but the way interacts with consumers may change.
A Sony rep said that soon the PSP would reach its promise. That could be a hint that the PSP will finally be able to download movies and become a more interactive partner with the PS3. Sony hopes to one day allow gamers to download movies directly to the PSP. A resolution depends on Sony's ability to find a way to lock movie content, so that you can't simply copy a pay-for-download film to other PSPs.
Expect announcements on some new PSP functionality within the next few months
