Despite of what it has been reported by WSJ about the delay of NGP release due to Japan earthquake, Sony has strongly denied the report. According Sony’s representative Satoshi Fukuoka, Sony expects to have no impact from the quake on the launch plan even some of their factories have been shut down due to the earthquake and critical radiation problem.
NGP has been scheduled to release later in this year, and Sony is planning to hold a simultaneous launch in several continent including America, Europe and Asia. However, to make sure they can escape from their claims when something unexpected happens, Sony has stated that they will keep alert and monitor the situation in Japan and will make adjustment as needed.
