Lets not forget also that for games that are also available on 360 and PS3 they will probably limit the game world size to something those older consoles can handle. The limitation there is the 360's dvd drive I guess which has less storage.
Obviously new area data is streamed into the console when required from hard drive or disc so I guess the real limit is how much storage is available per console and how much of that world has to be simplified to fit into 400MB of memory compared to 4-5GB.
