Id like to see the hunting rifle and the m4a1 return . Also one of the repeaters like trail carbine, cowboy repeater or even the brush gun either or lol

The Riot Shotgun in New Vegas is fun to use especially with the right perks. I hope it returns so that I can use the same play style I did in my last playthrough.

id love to see the anit material rifle and judging by the game play videos ill get what im after as i seen alot of pieces that could be used to build one

I would like to see the Marksman Carabine; if they give us the possibility to remove that scope and use the iron sights or an "ACOG"/laser it would be cooler.
Also, as a nice easter egg, the All American paint would be the cherry on the top.

ya the anti material rifle would be nice to as well. also the hunting shotgun i like using that its fun lol.

Dart Gun or variant thereof. The Dart Gun in FO3 or FO:NV - via mod - is one of the most formidable, butt-saving weapons I've ever used. Cripple an enemy's legs to prevent the enemy from full-on charging and allowing you to pull-off a few more rounds to finish the enemy off. It works wonders on Deathclaws as well as Casadores. On human or ghouls it is almost a one-shot affair depending upon your character's attributes.

I want a better version of the railway rifle...and it needs to be able to pin enemies (or parts of enemies) to walls and the environment.

The tommy gun is a must have weapon

Just for the benefit of those what to know if some of their favorite weapons are in the game, here's a list of all the weapons I saw in the E3 video.

Laser (Can be modded into a pistol, rifle, shotgun, or sniper)
Plasma (Again, can be modded into a pistol, rifle, shotgun, or sniper)
Pipe Gun (Once again, can be modded into a pistol, rifle, possibly shotgun, and sniper)
Hunting Rifle (Closely resembled a Remington 700 bolt action rifle)
Ripper
Super Sledge
Minigun
Combat Shotgun
Baseball Bat
Assault Rifle (In my opinion, most closely resembles a British Lewis Gun)
Cyrolater (Ooh, it's new. Possibly can be modded into a pistol, rifle, shotgun, or sniper)
.44 Pistol (May or may not be a revolver)
Junk Jet
Laser Musket (May be modifiable from default Laser)
10mm Pistol
An Unnamed Submachinegun (Resembles the PPsh-41, may be 10mm SMG)
Pool Cue
Wrench (Used in a special animation so it may not be it's own weapon)
Fat Man
Double Barreled Shotgun
Missile Launcher
Crossbow? (Seen in concept art, but not confirmed to be in the base game)

Hope it helps

I want to see the gauss rifle in there cause I love that gun, never go death claw hunting without one! And that's my favorite past time. I'd also like to see the marksman carbine come back in aswell as the shishkebab and powerfist.

I'd love to see the Automatic Rifle from Dead Money return, and A light Shining in the Darkness from honest hearts. Amazing weapons.

I'd love to see Light Shining in Darkness, Lucky, That Gun, and the Lever Action Rifle.

The FN-FAL from Fallout 2 would be cool to have since you can insanely modify weapons    

Lever-action Shotgun, it's cool, have the feel of Arnold

The Battle Rifle. Can't go wrong with the good ol' Garand.

The Anti-Material Rifle gives me life, although hopefully it can be modded in game with a faster reload speed and a better scope.

I'd like to see the Tesla Cannon back as well for the blasting of pesky robots and turrets.

I also really want The Kneecapper or a lever-action shotgun to make a return. Love something I can use at close range.

Other than those, I think I really want to see some new things as well. If there's a crossbow included then I can die happy because I've always wanted one for stealth kills in the Wasteland. I'd also really like a Machete type knife much like the one Bill carried in The Last of Us. Imagine taking on a building full of Raiders with a Crossbow and a big ass knife- in and out with no-one alerted.

God I can't wait for this game.

I hope they bring back the cowboy repeater honestly, even more so I really do hope they bring the various ammo back from new vegas

The .223 Pistol from Fallout 1 & 2 would definitely be a sight for sore eyes. I know it kind of appeared as That Gun and the 5.56mm Pistol in New Vegas, but those weren't the godslaying beast that the earlier Fallouts had to offer.

I'd say the .45 auto pistol. It's worked for the past 100 years, why not the next 200? Also I want to see the R91 and Chinese assault rifles make a return, especially with the new level of customization. The assault rifle we've already seen is unique looking, but a little bulky for my tastes. And definitely the hunting rifle. I'm a sucker for bolt actions. Although I hope they keep a right handed version, as I saw the bolt action sniper rifle in one of the gameplay videos was left handed.

I hope to see the assault carbine or at least something like it cause my first play through of FONV when I got the assault carbine it was like the only gun I used.
