>the games have had mechs as enemies since the start
Have they? Unless I'm missing something, all the robots you fight in the games were automatons reprogramed to kill humans, they were not piloted by anyone. These games have been around since the Famicom, the devs could have added aircraft and mechas a long time ago and I think there's a reason they didn't, land vehicles are tied with the identity of the franchise.
