I've heard that Sega is in trouble. they may be a reasonable games developer but unless they release a new console they may go bankrupt. Their company, if it did go bankrupt i was told would be put on the market for an estimated $100million. But the current Japanese owners have ambitious plans which may restore the company to it's former glory, but they do not have any plans of creating a new next-gen console.

that news article is old, it's dated 2006. ea will probably buy them out and will become their property in which ea will kill them once they use them for establishing a solid gaming foundation of titles. or what sega can do is sell some of their gaming rights to other developers and publishers to use.
