At E3 2007, Sony released information about a new version of the PlayStation Portable, regarded by many as Sony's answer to Nintendo's prior modification of the competing Nintendo DS - the Nintendo DS Lite. It is currently packaged in the PAL territories as PSP Slim & Lite. The new PSP is 33% lighter (reduced to 189 grams from 280 grams) and 19% slimmer than the original PSP system. The model numbers have changed to PSP-2000, following the previous region-based numbering scheme (cf. the PSP-1000 numbering scheme of the "old" PSP model).Wikipedia.
