I was listening to the newest Major Nelson Podcast earlier and he had an interview with Naked Sky, the developers of this past week's Xbox Live Arcade title: Roboblitz. Several people were worried when the game was released that they would release the mutliplayer aspect as paid content, much in the way Lumines Live has been rumored to include add-on content that was originally thought to be included in the game.
The developers stated several times that it would be a free download in an expansion pack of sorts, so it looks like there will be much more content than just the multiplayer gameplay addition.
