I recall hearing somewhere that Bungie wont be doing Space Battles until Destiny 3 or 4. However, a compromise that I at least want to see is the addition of an in-atmosphere air vehicle similar to the Banshee or better yet, the Hornet. At the moment, Destiny 1 only has 4 vehicles and a turret (though the heavy pike is just a different rendition of the regular pike). So far we've only seen footage of Sparrows, Cabal driven Interceptors (mini-tanks), and what will hopefully be a Guardian Tank (we still don't know if Pikes are returning). That said, we only know of 1 possible new vehicle, which gives us between 3 and 5 vehicles all up for Destiny 2 depending on what's returning, and they're all ground based. One of my biggest complaints with Destiny 1 that was never really addressed was the lack of variety among vehicles. While the new tank should add some new flavor to the mix, I feel it still pales in comparison to the line up of vehicles Halo CE launched with back in 2001, almost 16 years ago!
