I don't know for sure...just speculating here.
They are very close to the limit on memory so they may have had to choose between new hitting cams and fielding cams. With hitting being pretty difficult for the casual gamer, the more options you can give someone, maybe they will find a viewpoint that makes things a bit easier. I'd also be interested in the static fielding cam, but honestly I think that's something more for us sim people here, and it just comes down to space. I'm sure with the ps4 we will see plenty of new fielding cams.
