Sony: We haven't announced anything about a new PSP

On June 12th John Koller // Sr. Marketing Manager, PSP posted the following:

"The rumor mill is flowing about new PSP hardware and a PSP phone, and I just wanted to take the time to clear the air. We haven’t announced anything about a new PSP, much less one that would have any phone capabilities. As SCEA’s resident PSP guru, I’m thrilled to hear that there’s so much interest in the platform, but sorry folks, these reports floating around fall into the rumors/speculation category."

There have been rumors that Sony has a new slimmer version of PSP set and that manufacturing has begun. The rumors said that it'll carry an internal memory of a whopping 8GB. And battery life has been tripled.
Rumors quashed.
