The new Xbox Live Experience has been leaked and you can actually download it already. Why have I not downloaded it to give you a full review? The same reason I didn’t download GoW2 early, and the same reason I don’t use a mod chip.
I don’t think they will be too friendly with letting you guys use this. If you get caught with it on your box who knows what will happen. Maybe they will just ban your xbox live account, maybe they will ban your xbox live account and your xbox from ever accessing live.
Just wait, it will be out soon enough. If you decide to get it early, please comment with your first impressions of it.
