Yes They still have problems but their less frequent.
Xbox 360s vary in life. I have 2 xboxs one is the original 1st gen and its never failed. Upgraded to the 360 and it only lasted a year and had to send it back in.
original ~ $20-40 xbox 1st gen ~ $80 - 120 xbox slim 2nd gen ~ $100 - 140
Xbox Series
it is a 7th gen console
Old gen Xbox elite yes and I think for the Xbox s is well
normally the sonic next gen is so cool
wii or xbox ps3 sucks
about $40 dollars.
As the Xbox 720 isnt released yet, the price is unknown for the next gen consoles.
Because consoles needed the next gen graphics and hardware.
it will come out in 2013 -2015. Also the next gen console may not even be called xbox 720.
