Ah, I think they are doing that already. e.g., the mini-games, movie theater, shopping are all international. Unfortunately, the music, videos, virtual goods are regional because of existing rights. Others are based on deal making (e.g., RedBull Air Race is sponsored by Red Bull for US first, the Diesel clothings, mysoti clothes and other branded furnitures are probably sponsorships/placements struck by the local reps).
EDIT: The problem is with their compartmentalized infrastructure services (e.g., game launching, ad hoc party gaming, chat, etc.) and their inability to align Home schedule with the game release schedule and footprint. Most of the Home Spaces are released long after the game. And when released, some regions may not get it.
