Prison Break Series 3

I have just seen a trailer for Prison Break Series 3 which is going to be on Sky One starting on 24th September. I can't wait, unfortunately I will probably miss loads through working, as we can't get Sky One here! I will have to set the Sky Plus to record the whole series. As you know I loved the first 2 series' and so I hope that the third upholds the good writing and acting. I wonder who, apart from the brothers, will be in it from the original cast.
