No because lizards have tails, elites do not There are literally hundreds of reasons why sangheili are nothing like lizards. anyway, they will bring back playable elites, the allied elites and the storm elites because halo 4 revolved around the Infinity getting trapped on requiem, where Jul-mdama had gathered members of the covenant who had not been informed that the war had ended. now that the ship has been reunited with the rest of the military, there will most likely be larger, more action packed battles. I believe that one of the main enemies will be dr.Halsey, because in the ending cutscene of spartan ops, she told jul mdama she wanted revenge on the UNSC, mainly on commander palmer for shooting her arm off.

Just to clear everything up, the Sangheili are not dinosaurs but reptilian aliens, they should bring back playable elites mainly because, humans are boring... lets face it, in nearly every single game out there you play as a human its just plain, wheres the imagination? games should be about doing things you cant do in real life, i play as a human every day, and its boring. and yes, NO ONE WANTS TO PLAY AS A BRUTE, if i wanted to play as a hairy freak i could just go play king kong and id rather play ET the game than something like that. when i got halo 4 i was disappointed to see that there was no prefered species section in the customisation menus, just as i was when i couldnt customise my elite in halo reach. i think that if they do bring playable elites back we should be able to customise them unlike in reach
