For now, we can only guess at the price of the Next Generation Portable, but there's a reason for that- the device is still in the prototype phase.
Sony boss Kaz Hirai told Impress Watch (via BeefJack ) that until they've finalized all the technology, they can't accurately predict a price or estimate the life of the battery. He does say they'll "make sure it's all in line with what's expected from the market," but as a direct comparison, remember that Nintendo's 3DS will have a battery life of 3-5 hours and have a price tag of $249.99. The NGP should be able to come in around there, right? Many seem to be a little disappointed at the 3DS battery life and price so maybe Sony's ultra-advanced little unit is in good shape at this point. Of course, EEDAR analyst Jesse Divnich told us it's "unfair" to compare the NGP to the 3DS but let's face it…everyone is gonna. For our part, we're hoping it doesn't cost more than $299, and the battery life is a good 5 hours. If the games are there, that would make the NGP worth the investment, in our eyes.
But everyone has different requirements and requests when it comes to stuff like this, and there's no chance of satisfying every consumer in the world. Let's just hope the NGP satisfies quite a few.
