I agree with everyone here. Instead of being greedy and just selling exclusives to the highest bidder, just plan to release DLC for all platforms. If they want to take a main game and tack on episodes instead of whole other games for filler, that would help a lot!
EX: Between GTA 3 and 4 you had Vice, SA, VCS, and LCS. Maybe episodic content is the new thing instead of "filler games"
