So, Sony shall continue to go down the route of just producing consoles for however long they want...
Now this is all speculation, but does this mean a ludicrously high price for NGP? Look here:
"I think the NGP needs time to mature and get adopted by users. So, for the time being, both platforms will coexist,"
What does "time to mature" mean exactly? Does it mean that the price is high so they don't see it selling well? Are Sony waiting for a price-drop? They did the same thing with the PS3, and it worked well for the PS2, but the high price and lack of games library hurt the PS3 in early years, coupled with a late release.
Will Sony do it again? Or have they learnt that great graphics high price=lower sales?
