Yeah, the anime series isn't very clear...The mystery of Sai on the internet was not publicaly revealed but I think Touya knows about it. I don't know if Shindou will surpass Touya, but it is nice to know that Touya recognizes Shindou as his rival now. I think the manga goes past the anime, so if you read that, your questions might be answered...
