Five days before we thought it would be arriving, the Nintendo Channel has just been released onto unsuspecting Wiis. We're currently feverishly downloading it, so we can't give you the skinny just yet, but we know that it allows users to write reviews for WiiWare titles they've played and provides sortable lists of upcoming games.
