Oh WOW you are going to have fun!
They're so sweet and they will be very close to each other. I know you are so excited and ready for those two babies. My two that were raised together have such a sweet bond. They usually like to be touching when they nap too. Most anything we do they watch to make sure the other one comes along. Made training a little easier because they follow one another even to potty time. I can ask who wants to potty and everybody runs to the door. Have fun with your sweet babies!
