There are a few issues when you are using the MLB camera angle for batting that i am a bit concerned about...
First of all, mlb is visually stunning. Even though your game looks great also, it definitely is not in that level yet. So while having such a close camera in mlb is not risky, it might be for you guys as this might showw off the flaws in animation or model or w/e a bit more. But looks like you guys are willing to take that risk so
2nd of all, this might be a big issue for casual gamers. as someone mentioned broadcast view is mostly the way we watch/experience cricket while the first person/behind the batsman camera is the way we experience cricket when we play it ourself. So if lets say we are playing with an international player, looking at the field from the broadcast view feels "right" but in a career mode it will feel just "right" from the mlb's camera angle. But in the end i guess people need to suck it up and get used to the new way, specially if it is a vastly superior way than anything done in the previous games. Lets hope it does not put off the casual gamers.
