Ok... just ordered it from Amazon.com! Will have it in my hot little hands and be feasting my eyes on it on Tuesday! 
Can't wait to see FNIT in fullscreen... from what I have heard it's even more amazing! 
You see more of Jack's left hand cradling Ennis' head in SNIT.
FNIT you definitely see more of Jake's butt and his thigh ! :`)
More of the hand grabbing in the throws of their action !
Uhhhh. I need some ice water !

I love FNIT, but the part that makes me kind of laugh every time , is when
Ennis' head goes kathunk on Jack's backside when he finished.
I just can't help it. The boy was spent !
