Will my Siamese cat like another cat?

Our Siamese cat is 2, we would like to get another Siamese cat for him to have as company and to play with. Does anyone have experience with the breed, or just with introducing a new cat to a current cat?
Thanks.
Update: Our cat has a good temperament, but has been an only cat since we got him, so I guess we dont know what to expect.
Update 2: Our cat is neutered, and this new kitten would be a boy and would be neutered as well, when he's old enough.
