As long as the accounts are saved on the memory device the maps are on it should work. So when theyre signed in and it says "select save device" click the one with the map packs.
Nope, all in-console purchases requre xbox live.
none. Xbox is a completely different console.
You don't. Games are designed for a console and do not play on a different console
You recover you profile on that console you want the avatar on and then you have your profile, games and everthing from your other xbox to the other console.
no they are two different manufacturers
Because they are two different systems, sometimes it might take longer to develop the DLC on a certain console.
No, i think they have a different format of disk. :)
yes, unfortunately you have to buy a separate xbox live membership for a different profile even though there on the same console.
Console, no. You can connect to an Xbox from a PC.
The Maps and DLCs can not be loaded with a USB so they are not available for the PS3 or Xbox 360 except for downloads directly to the console. Map packs must be purchased and then the Playstation Store or Xbox market is the only site that can download and only to the internet connected console's harddrive. The PC games maps are found in updates to the game
No not yet, although they are working on it.
if you mean the xbox pro console then of course you can you can go on live with any xbox console
