Contrary to reports as early as last week, according to SCEA there is no plan to redesign the PSP in the near future, and that includes adding a big brain or telephone capability to the system. This comes directly from the mouth of SCEA's Sr. Marketing Manager on the official Sony blog, so we're inclined to believe him.
It doesn't mean that there won't ever be a redesign, or that it's not already happening, but it does mean that Sony's not ready to roll out that information at this time. This is nothing but good for them, though, since interest in the PSP had clearly flatlined, and now is coming back a little.
