Yeah this is pretty much the case, I did a side by side comparrison for the cards in my Victorias box and the changes are pretty minimal to the point where you can pretty much just remember them.
Victoria: Another One? Sacrifice a Ronin, not discard as per V1. Taelor: Hard to Wound is Hard to Wound 1 Bishop: Knock Out is a Melee strike (it already had a range of 2, so its fairly easy to recall)
And as far as I can tell that's it. Take a look at your own cards and it might not be so bad.
