Looks like the Sony PlayStation Portable (PSP) could be in danger of missing its shipment schedule if games developers don't pull their finger out and get some titles out on time, it has been revealed. The PSP is slated for a Japanese release at the end of the year, which it is now in danger of missing. Many concerns have been raised about Sony's misjudgement of the device's development cycle, which late console rollouts to testing and other problems hampering development.

The PSP is due to launch in the US and Europe by the end of March 2005. Apparently.
