so here are some official data of the 3 consoles
Wii 2 or Super Wii
the successor to Nintendo’s Wii is commonly called “Wii 2” and “Super Wii." Shigeru Miyamoto mentioned at E3 2006 that the successor to the Wii would include high-definition capabilities. graphics a bit more high of those of the ps3
Xbox 720 of Xbox 3
The successor to Microsoft’s Xbox 360 is commonly called “Xbox 3” or “Xbox 720." Although their chief concern at this time is to lower the cost of the Xbox 360 and had not started on the Xbox 720’s development as of November 2006,[3] Peter Moore has supposedly told EGM that the next Xbox console would be released between 2011 and 2012.[8] Microsoft EMEA veep Chris Lewis said in October of 2006 that work had already begone on the 720, however he did not say just how far that work had gone.[9] It has been speculated that the Xbox 720 will include a camera capable of tracking the movement of its users and not just the controller.[10] Microsoft has confirmed they are going to begin developing and producing their own computer chips which will probably be present in the 720. The research will be done by two groups, one in Redmond, Wash. and one in Silicon Valley. The man heading the Silicon Valley research team says that it is probable that voice interactive technology would be incorporated into the next Xbox console.
PS4
Sony has stated that there will definitely be a PlayStation 4.[4] At this point they are the only company to announce that they will be involved in the eighth generation. Nevertheless, no information or theories have yet surfaced concerning what Sony will do with the PS4; however, they have stated that it will be released after 2010. Sony says they are planning for the PS3 to have a life span of about ten years, meaning they will discontinue support for that system in or around 2016. However, as Sony believes there is room for “significant overlap” it is probable that the PlayStation 4 will be released well before that, possibly 2011 according to one site.[12] In an interview with Sony’s president of worldwide studios, Chuck Norris says he considers it highly unlikely the PS4 will utilize disks, instead you will download all your games directly to the console.[13][14]
these may placed them too expensive
