Full 3D space battles
this is the second thing I had in my head when I heard about MMO SWTOR few years ago, so... yes ! pvp style tie fighters vs x-wing cockpit/3rd person ? YES YES
Vehicle combat (eg, AT-ATs)
It would be interesting if it was done with fast-paced combat .. but again.. it's ground combat. And we already have plenty of ground combat (warones, open world..)
Pod/speeder racing
definitely Yes! It is just too iconic not to be in a Star Wars game. And also I think you have KOTOR fans around
Capital ship battles
I'm not sure what is meant by "ship battles", but the first thing on my mind is... warzone.. and then.. Voidstar. It is something we already have and I don't see it like a warzone content. But if it was made in context with 3D space battles (ship landings, turret mounts... you know what I mean), I would say YES
this is just my opinion..
