NGP's Battery Will Apparently Last For 4-5 Hours.

A report on Eurogamer pegs the device's battery at a reasonable 4-5 hours, comparable with the notably inferior Nintendo 3DS.

According to Eurogamer, 6-8 hours was Sony's original target for the device, something they may still achieve with additional development time before launch. Eurogamer also mentions that while pricing for the NGP has yet to be announced, Sony will be "making a loss" on each unit.
