Yes they will be making Xbox-720 in some time
no its not because pse is the best sytem in the world
my xbox 360 has already bin updated can i make a new profile
No
No, just recover your gamertag on Xbox Live.
the original xbox is to old so they dont make new games for it
if you didn't make it into a gold you wont be able to.
In the solar sytem there are 9 planets.There is also a milky way. I think that some people found 2 more new planets.
Next Xbox 720 to launch in 2011-2012 according to Microsoft at the moment though, they only have the xbox and xbox360
By disconnected, I am guessing you mean banned forever. The way to fix that is make a new windows live account, wipe your xbox, and make a new xbox live account.
factory sytem
If you account is connected to live then you should just be able to login on the new xbox. Assuming they are both 360
no there is not. they dont make new games for original xbox anymore. sorry.
