Have you guys read the actual translation? It doesn't even mention FF or DQ, they want to focus on multiplataform that does not mean that FF13 or DQ9 will flirt around.
We could see future Saga games, Front Mission games, Full Metal Alchemist games and FF spinoffs go multiplataform, but the major games will most likely stay.
I believe is not 8% but 12%, still that gives Sony a say in many SE decisions look at it this way:
If a sickness spreads to 8% percent of your body, lets say your right leg, and this sickness doesn't let you move the leg so when you decide to move around you can't cuz a part of your body even as little has 8% percent doesn't let you. Its the same case, Sony will always have a say in SE decisions, even if they're not big part of it they're still part of them.
