-i am interested to buy an xbox 360 arcade last week of september at walmart.i want to know if how much space will occupy if i save different kinds of games and just overwrite it over and over again so that they will remain as a 1 saved game file and everytime i play while im in the game.will the spaces deduct if i just overwrite it?

-Can I play all xbox 360 games on xbox 360 arcade?it will still play even though theres a LIVE word on the right side of the casing right?

-Do you think there will be Resident Evil 6,GTA 5 and other good game sequels that will still be made on xbox 360 or ps3?

-can i insert burned discs that has music?will it play?
