The successor to the Sony PSP, the NGP, may see a delay until next year after the recent earthquake and tsunami rocked Japan. Sony is merely thinking of delaying the launch of the NGP, but with all the troubles the tech giant has had at its manufacturing plants, it seems all but likely. That should be good news for developers to get more products out when the handheld does launch, but that also means the Nintendo handhelds will gain even more ground in the market. Sony Computer Entertainment of America President Jack Tretton said that one of the three main regions (Asia, Europe, and the US) may still receive the NGP by year's end, but didn't say which one. Sony was hoping to have the handheld out in time for the 2011 holiday season, but production at seven different plants in Japan have been suspended or slowed down in the wake of the disasters.
