Rule of thumb: If it exists in name only or on paper only as a rumor, it's probably just that. A rumor. I don't doubt another XBOX and Sony console are due soon; the 360 and PS3 have been out for several years now. If there is a new console coming in 2013 then it's definitely still in the planning stages right now. It takes YEARS to make these machines, people. I don't think it's going to be ready by 2013. Maybe 2014 or something. Development of the technology and better processing, rendering, etc. takes a while.
I have to disagree, consoles can be repaired and tweaked just as PCs can, beoza. I know people who have modded their old XBOX consoles, people who have given them larger hard drives and stuff, etc. With how much these machines can do it's not surprising that there's a community out there devoted to tweaking machines. And obviously, consoles can have parts replaced up to and until the console is rendered obsolete and support's dropped - just like with PCs.
Consoles are supposed to last a specified time? Have to disagree there too, sorry. I have an SNES in storage that still works more than a decade later, and the only reason it can't work now is because TV hookup methods have changed. My best friend has her N64 she got the day that console came out, and it still plays just fine. Until recently my XBOX was hooked up to my downstairs TV and it hasn't had a single problem; the only reason it's not playable now is because my XBOX 360's hooked up there. I bet you'll find more than a few NESes, Genesii, and Megadrives at your local gaming warehouse too, so I don't even wanna hear how "consoles only last so long". The components themselves do, yes, but as long as you can find replacement parts and treat the machine gently, the console's good to go.
