Pretend? I was asking what IPs do they have that can realistically sell well while pushing hardware to a reasonable amount to get their momentum rolling. Crackdown doesn't seem like a system seller, and Gears of War isn't as new and shiny as it used to be. It can probably sell well(though the franchise doesn't sell more than 3 mil copies per title), but I'm not sure of it's potential to move hardware anymore. It seems like a franchise which will sell to the faithful, rather than something that was not only amazing to look at but offered a fresh gameplay experience last gen.
So yes, which exclusives do they have which can fill the criteria I explained above?
