I said something similar early this year. Sony is still in debt, though they have sold a lot of buildings and everything else. Thats why they made the PS4 as approachable as possible to gamers. PS3 had a difficult launch due to price, deleting of the BC etc but it still sold very well. An i know they are taking a hitting on tv market etc mostly i think due to cost. Other companies make much better electronics for less money, Sony have always sold on their name.
But maybe its just a whole different ball game now compared to PS1 debut. Games cost more and more every year. Consoles cos more to make as the race for better graphics and performance increases. Maybe its becoming a very expensive business to sell a console. But if they do stop making console, i doubt it as PS4 will be a success, then they will still make their great games. An maybe they will just let MS spend billions on making consoles and Sony will just reap the profit off the gaming side.
Although, i wouldnt mind if MS and Sony team up and bring out a console. Play Box? X-Station? Though would let Sony deal with the hardware side as they are way more reliable.
