Yeah i think the same unless manga proves otherwise, the only thing that makes me think otherwise is the Kyubi incident, but i think with a normal Sharingan the Kyubi could be controlled too.I don't think tobi has one right now in his eye socket. It has never shown more then three tomoe and when he uses his space\time ninjutsu it only shows 3 tomoe. :\ Kishi is killing us right now. Also I'm pretty sure you can control stuff with a normal sharingan if you're skilled enough. Like how sasuke controlled manda and placed him under a genjutsu so he would listen. Tobi is pretty good with his sharingan.
