1. Sony
Sony takes the successes they have had late in the console cycle and the investments they made in New IPs and thrive. Their online infrastructure will be even more improved than it is at the end of this year. Sony will continue to not charge for online and launch at the same time as Durango. Microsoft's focus on advertisements and monetizing features that are free on every other set top box will have them linger behind a world wide selling system in the PS4
2. Microsoft
Microsoft will focus on improving online feature in their device so that their vision of the window into the living room will come to fruition. Microsoft will make decisions that improve 720 as an entertainment hub, that will harm it as a gaming device. Monetization of features through the rising cost of Xbox Live will make Microsoft a lot of money, but will prevent the system from being a runaway success. Microsoft's lack of diversity in studios will leave Microsoft at the whims of 3rd party publishers. Parity with the other next gen console is crucial.
3. Nintendo
Nintendo's WiiU console will be a success in Japan, but it's successes elsewhere will not reach the level of the Wii and fall behind the other two console manufacturers. Nintendo's WiiU tablet will splinter install base and cause developers to shy away from porting PS3 and 360 games to their system during the 2 year window that PS3 and 360 third party development will still be receiving non-sports titles. Nintendo will come strong out of the gate in the United States and Europe, but will only continue it's successes in Japan following the establishment of the two other two next gen systems.
