What we've seen is only a small taste of the game rather than a comprehensive overview, so it's really easy for people to want every wish granted. Though I don't expect to see a new kind of personal vehicle for Guardians in the Red War Campaign, I hope at some point we get a "Hawk" with weapons for Patrol/Story and PVP modes that cater for it - either as a chassis we earn and build up to completion via a quest, or perhaps discover in the Lost Sectors randomly and then upgrade over time like other gear.
