I am going to go out on a limb here and say that if Sony pulls another PS3 situation where they charge a large sum of money for their fourth console, they might as well forfeight their standing in the console market.
Look at this way, if Sony had made the PS3 cheaper and released it for $300 back in 2005, the console would have sold out so quickly and they would not have suffered financially for this blunder. The established brand of the Playstation would have been enough for people, and loyalist, to buy the PS3 and make them lots of money. Instead, they pulled the **** they did and lost a lot of customers to both Nintendo and Microsoft. Although these customers eventually came back to Sony in a about 2009. They are still laging behind because they are currently where they should have been two to three years ago.
I am just curious to see what Nintendo has in store for their next console. It will most like be $300 even and will be on par with atleast the xbox 360 in graphics. One could argue that the 3DS is simutaneously the DS successor, but in some way, the wii 2 at the same time. I do feel as if Nintendo is going to emplement some kind of cloud computing for the wii 2 when it releases, which I am wagering that it will be 2012.
