I apologize in advance if this has already been said in this thread, but it looks like Jimmy has a new batting stance this year. I hope the batting stances and pitching styles have been updated in more detail. (Yes, I know there's another thread on that topic.) Looks like the umpires got an updated attire as well..
Edit: On the thread, Video Interview: Ramone Russell - Revamped RTTS, New Training Modes if you closely watch the tv you can see Josh Hamilton and Aubrey Huff got new stances as well!
