Here are a list of things I want/expect to appear in Halo 4, along with what I expect not to.
Lets start with What I will expect in Halo 4
otherwise known as things that havent been confirmed nor denied yet.
Gravity Hammer: I’m sure we all wont be surprised if this was in the game, it’s too damn fun a weapon.
Plasma Rifle: now before any of you say “Storm rifle is replacing it!” I dont think of the plasma rifle as being a rifle, but more of an SMG. besides, it has all the characteristics of an SMG: it has a high rate of fire, compact size makes it dual wield-able (canon wise, I know DW isnt in H4), and powerful at close range. I also dont expect 343 to remove one of the most iconic weapons in the halo franchise.
Concussion Rifle or Equivalent: for two reasons - 1) they need a covy equivalent to the sticky detonator, which seems to be the new grenade launcher. I doupt they will keep the brute shot though, so that’s why I wrote CR instead.
Plasma Launcher: similar reason, need a covy equivalent to the Splazer. it charges up, it fires, it is often 1SK
Feul Rod Gun: again, equivalent to Rocket.
Hunters: though non of us really knew why these space worms worked for the covenant in the first place, I doubt they’d stop fighting with them now considering a few other species still fight with them too. again, a very iconic enemy in the Halo franchise. speaking of space worms…
Scarab: one of the many flaws reach had was the lack of scarab fights, but that was so you could get the feeling of being rushed; you had to deliver cortana as quickly as possible, so you didnt have time to fight giant mechanical beetles. but, with halo 4 being an actual sequel I see scarabs in our future.
What I’m sure wont be in Halo 4:
Target locator: no real reason or evidence, just a feeling. also wouldnt make much sense there being no firefight now.
needle rifle: now although I’m sure this isnt gonna be in the game, I was really wishing it would, we need more needle weapons! I was actually thinking it would be a good equivalent to the BR because of its fully auto function making it more close to mid range than the carbine. but who knows? 343 might add it in the last minute and we havent been informed all of the laodout weapons yet. I’m sure we’ll have a good amount to choose from, which brings up my previous statement about the plasma rifle.
Engineers: after ODST, I’m sure the covenant stopped relying on these flying squids, so I dont see why they’d ever return.
Pod Launcher and Flame Thrower: highly unlikely. sorry but I dont have anything to say about these two other than I just dont see them happening.
What I’m not sure will be in Halo 4
Spiker: now I’m neutral on this weapon; I see it as a slower plasma rifle, but without it, it’d be kinda weird having only 1 brute manufactured weapon. (mauler comes to mind)
Brutes: this one is on the very edge of “not sure” and “pretty sure” if it’s gonna be in the game. I have high hopes it will be in the game though. in Glasslands, it clearly stated the Elites couldnt tend to their tech without the brutes, being the engineers of the covenant and all. besides, someone needs to be holding a Gravity hammer for us to kill and take it from 
drones: in the similar pool of brutes in which I’m 10% sure they’ll be in and 90% not sure if they’ll even show up. then again, I dont see the reason to removing enemy variety from halo.
brute manufactured vehicles: I just WISH so badly that I could have just my beloved chopper back. gonna miss ya, Wrex.
Revenant: dont know if 343 has some other warthog equiv up their sleeves, but only time can tell.
Sentinel Beam: kinda leaning towards the “removed” side of my thoughts of whether or not it will show up, but I’d be very surprised it will make an appearance since now we have actual forerunner ordnance and not just scrap metal from a sentinel.
What I cant come to peace with that wont be in Halo 4
(note I may sound a bit obnoxious here)
SMG: WHY? WHAAAIII?! seriously though, why?! make it a secondary! nerf it! make it require 75% of the clip to kill! anything! please! I keep thinking it’s in the game but it’s not! my brain keeps saying “just wait, I’m sure there will be more weapons” I just want a proper small arms weapon that ads variety in the small arms department! PLEASE!
Grenade Launcher: we want the pro pipe. we want the pro pipe. we want the pro pipe. I can not stress that enough. oh well, hopefully the sticky D will at least satisfy some of us.
That’s all I have, but let me know what you guys would expect/want/not expect/not want in halo 4
