We'd love to have a magic wand to fix any issue, but we don't, so we have to develop a patch, test, retest, submit and so on. It takes time - it's frustrating for you lot though, and we understand that. But we haven't forgotten about you and the Xbox 360 owners that expect a fix, and we're working on one at the moment.
