The eye of Sauron may very well be canon.

"Far off the shadows of Sauron hung; and then he saw, rising black, blacker and darker than the vast shades amid which it stood, the cruel pinnacles and iron crown of the topmost tower of Barad-dûr. One moment only it stared out, but as from some great window there stabbed northward a flame of red, the flicker of a piercing Eye; then the shadows were furled again and the terrible vision was removed."

From the books, as Frodo and Sam are on the slopes of Mount Doom and see Barad-dûr. My theory on what the eye of Sauron is is a flaming extension of his own soul, able to observe things his body cannot, or an image placed into the minds of most people in Middle-earth. Even the movies support this to some extent, as Sauron was originally intended to fight Aragorn in his physical form, but was replaced by the troll. Even you pointed out that Sauron had a physical form in ROTK, although it was obvious that it had been remade since FOTR (which is why I said to some extent).

Here's the blog where you talked about his physical form: []
