Actually no, Deadly Aliance's symbol is a Roman Numveral 5 design. And besides, none of those games have specific titles. Look at MGS4. It's called just "Metal Gear Solid 4" not Metal Gear Solid 4: Guns of the Patriots. So, MK7 could very easily have a name with the number.

And I totally forgot about the new Tekken. But, fuck the FFVII-remake. REmake is the best remake ever.
