I'm assuming it will be just like any other time a card portfolio is sold or transferred (Costco Card: Amex -> Citi, REI Card: US Bank -> Capital One, GM Card: Capital One -> Marcus (which is Goldman, ironically I think they want to get rid of this card too), etc...). Unless Apple discontinues the card completely, they will choose a new bank, that bank will take on the existing portfolio, everyone will get new cards (maybe numbers depending on how they did the BINs)...but with the physical card not having a visible number, the apple pay card being able to be automatically updated, and the virtual card's number being right there in the app it should be pretty painless.
Since Apple manages the whole thing through their own app and not a Goldman Sachs app, it should be fairly seamless as everything should look the same and you won't need to make a new login or worry about how to start paying a new bank. If there's new cards to be issued it's likely it will just show up in the Wallet app and they'll mail you a new physical one. Last year Apple moved the Apple Cash card from Discover to Visa and most people didn't even know that happened. There was even a button to switch it over sooner if you wanted to.
With the Savings Account I expect it will be similar as long as they can find a bank willing to offer a similar APY. Especially for people who just use it with the Apple Card and don't deposit directly to it using the routing/account number, you probably won't really notice.
source: all speculation, but I have worked extensively in payments for years and have launched banking products.
