A new dishwasher = a new faucet too?

My birthday is this weekend. As a present, my husband bought me a dishwasher. (No need to kill him, I wanted it.) However, we don't have room for a built-in dishwasher. Instead, we got a portable one that hooks up to the faucet. Unfortunately, this means we may need to go shopping for kitchen faucets now. Our house is an older one so all of the hardware in the house is pretty old. I'm not sure if the dishwasher hookup will fit on our current faucet. But that just means more presents for me, right?
