Stance might look weird in trailer but it wont be a problem during gameplay coz in real time you wont notice this. They have done some really great stuff for the game which no one has ever done before. So lets appreciate that. Here is some stuff which i noticed in trailer:
1)Players bending and turning while taking runs. In one occasion the player touched the ground with his other hand to maintain the balance. That was flipping awesome. (46th second in the trailer)
2) Player's eyes were focused on he ball while batting. So no more looking east hitting west shots.
3)Jamie or someone in the Dev team is big fan of Sachin coz the cut shot Pietersen played in the video was not the powerfull cut that he usually plays. It was a gentle cut over the slips.
4)For those who are complaining bout he clarke shot where he was aiming for mid off and shot went mid on: Well maybe clarke was on low confidence when user attempted that shot. Thus instead of going to mid off ball popped toward mid on as a result of inside edge. Noone saw the remaining of the shot but this is most likely explanation otherwise Playtesters Like Lazy and Kamy would have posted something bout it too. I remember Lazy posted somewhere that the physics engine is very good in the game and you get a lot of inside edges on thighs body, and nuts
... So it was just a inswinger which user failed to interpret and tried to play a backfoot shot towards off side, hence got a thick inside edge and ball popped towards mid on.
