That's not absolute proof, that's Zaraki's ignorance to his Zanpakuto's existence. When I'm not in class I'll try and find the episode where Zangetsu tells Ichigo that Zaraki's soulslayer is crying out to him but he isn't listening. (It's right at the end before they both unleash their final attacks).Alright. He says it just after the fight really begins (when Ichigo managed to cut him).
For the absolute proof I provide you....

"My soul slayer ain't got a sealed form to begin with. This is my soul slayers true form"
2:00-2:10
"The reason I don't seal my soul slayer is because my spirit force is so huge I couldn't seal it, even if I held it in as hard as I could"
-edit
I hope it's not illegal to show a page or two from the manga, if it is, a mod can remove them.
Anyway here it is in the manga where Zangetsu tell's Ichigo that Zaraki's sword has something sealed inside, indicating his sword hasn't been released and is therefore not in Shikai mode.
chap 113 page 7
