It's important for us that all online players could show off new content when they go online and unfortunately it wasn't going to be possible to do this by supporting the lowest common storage denominator, the 64Mb Memory Unit, either in size or data read speeds. Crucially we also didn't want to split the playing community between those that have updated data and those that don't. We saw this as vital in maintaining simplicity to all online users; different players having different content packages wouldn't be able to play online with each other.
