When will he start to look like a goldendoodle?

My puppy just turned 7 weeks old yesterday. Everyone thinks he's a golden retriever, and we're a little afraid he will look like one when he is older instead of a goldendoodle. His mom is 3/4 poodle and 1/4 golden retriever, and his dad is full blooded golden retriever. Is there a possibility that he will always look like a golden retriever? I know that it's a little too soon to tell because he just has puppy fur. When do you think he will start (or if at all) to get wavy or curly fur?

Thanks for all of your replies. I am brand new to the site, and I am really happy that I found it!
