Well, if you liked Gears, then you should like Uncharted (I know it's not the same thing, but at least the cover system is the same...system), and MGS4, which has everything (including First Person Shooting).
But if you don't have enough time for games anyway, and you only like shooters, I don't really see the point of it yet. Wait for the elusive price drop, and then get the gaming console that will work well as a future proof movie player, if all else fails.
