Variety is the spice of life!
If your training is working, that's the big thing, but if you keep rolling out the same content it's virtual punishment for those doing the pointing and clicking. Look at the segments you believe to be critical, particularly those that have not changed and replace them (this year) with live segments about how things are done within your bank; e.g. if you have a teller segment about cashing checks then make up a training segment about the procedures for cashing a check in your bank.
