Long Live the Confederation!
I just want to ask: Are you saying that there should be no confirmed list of titles to be removed from X-Box Live Arcade?
There is no such list at this point. Given the unpopularity with which the *suggestion* has been taken around the internet, it's quite possible that we won't even hear anything of the concept again. Beyond that, we're not dealing with a magic robot that follows exact rules - there's reasons why it's very easy for Microsoft to kick out small third party funded games and why it's less desirable for them to remove games from their favored corporate partners.
