It's been three years since the PSP came out and it's enjoyed strong sales, especially recently. Big releases, like FFVII: Crisis Core and God of War: Chains of Olympus, and a new model have kept sales around 200,000-300,000 units a month, in North America alone. There is now however, virtually no high profile title coming out for the PSP for the foreseeable future. With absolutely nothing to keep the PSP selling, it is seeming more and more like a spent force which is why I think Sony will unveil their next handheld at this E3. I have no source on this, not even a rumor. Just a gut feeling.
