Good topic. I'd like to see a few things:
Co-op, split-screen and online, campaign and multiplayer.
More civilians in the urban battle settings; Helghast doesn't feel like an actual place without people or stores or dwellings. It feels like all the gunfights take place on an abandoned movie set or something. They should add civilian-type Helghans, and maybe introduce a kind of dynamic mechanic where the civilians attack with whatever's at hand (rocks and debris at first, and they can even pick up fallen soldiers' guns) if you fire on them.

A little more intrigue/thriller aspects; rather than just all out action all the time. I liked the segment in KZ2 when Sev gets separated from the team; maybe a sequence where the main character has to escape a POW camp or the like, rebuilding his arsenal from fallen foes.
Different environments; maybe not beaches or jungles, but different kinds of cities or bases. Certain Helghan outposts can have different design philosophies or environmental circumstances. I loved the desert stages: maybe an naval outpost or cruiser. I know that it's supposed to be a monolithic, totalitarian state, but just for the sake of variety, I'd like to see aesthetic variations on that theme.
More sci-fi-style weapons; like the Electricity Gun.
Slightly tighter camera control; maybe it's just me, but the game's a lot harder to just pick up and play without time to acclimate to the floaty camera. I don't mind the heavier movement, but I'd like more precise camera control.
Bigger maps; I loved the 32-person battles spread over huge maps, I loved sniping people from across maps, I loved rolling out with my whole squads and getting into skirmish after skirmish on the way to objectives. I hated 'nade spamming and killfests in the smaller, more cramped maps, especially the DLC ones. Maybe it's just me.
Better story; There has to be something more to explore in this world than just space marines killing people/things. Maybe this isn't the franchise to do it with, but I just want something a little bit more outside of the box. Not a lot, just a little bit.
Online character customization options; just a small thing, but I enjoy the options in Halo for instance, and I think shooters are more fun when you can keep a look out for specific people based solely on their custom character design.
That's pretty much it for me.
