I played it "Move-style" at my local BB and there was a small delay...I'm hoping it was due to not having calibrated the controller beforehand but I have a feeling that wasn't the issue...the delay is much smaller than it was for the HR derby mode last year though...
Overall the controls felt great though...a lot of fun for an exhibition game or playing with the kids...I've been waiting for a long time for full motion controls in a "real" baseball game...
