Yes that is true Blackwiggle, but I don't think SL is going to make the same mistake twice! That means seperating the online community like they did with Pulse.
So I really hope there will be these download keys like Everybody's Golf, what Lunar is talking about. Everybody just has to download the game including Fury, but the ones that don't pay can only join online races with tracks from Fury, but not host or play campaign or offline.
