Plus, why would Izuna wear a mask to hide his identity? It would be rather anti-climatic to hide his identity for this long, only to reveal him and have nobody recognize him or know who he is.
Honestly, if you're not convinced by this point that it is Obito, then it's going to take seeing his face and having Kakashi say "...O..bi...to...!?" Because Kishi has done everything possible to let us know who he is, except for show his face at this point.
