Walleyes, Janzhaus has been around for awhile, they are reputable breeders with good bloodlines. You have made a GREAT choice. Post some pics when the little gipper finally arrives.
If I can offer you any advice at all, train him well and you will have one hellava dog and protector. The GS breed is loyal and fearless, they will protect you with their life. They love being around people and a part of the family. Involve them in family outings and expose them to your grand kids at an early age. There will come a day when your male German shepherd will suttly challenge you to see how far he can push, they are not stupid so be a strong pack leader at all times. If you have no skills at training them get yourself a good book (and I can recommend a few) or send them to a trainer. It will be money well spent....THEY have to be trained or you will run into behavioural problems.
Here are a few pics of my boys. (and gals)
