I don't want Gears 3, not for a long time.

Take out proximity grenades and take away the ability to knock players over with smokes. Seriously, it is too much and though a good player can beat those threats they are seriously annoying. Also what happened to creative map design? Jacinto and Pavillion are pretty much the same maps. Stasis, River and Ruins are pretty much the same maps. And the rest of the maps feel like similar copy and paste jobs as well sharing elements between them. After being a fan of the MP in the first Gears, Gears 2 feels like overkill. Epic added too much junk to MP and the maps lack the style of the original's as well. SP is great, but you can't just keep adding more and more crap to MP, it feels like a mess to me.

Online that fucking works. I cant even bring myself to play this gears2 anymore. I have better things to do then wait..... and wait..... to get in to a match. What a disappointment. 

Horde mode in Gears of War 1 style multiplayer, no one-off matchmaking bullshit.

A storyline that CONTINUES as good as GOW 2, do not fuck that up please.

More of the same.

...and Horde mode as the Horde (tho I'm hopin that will actually be a G2 dlc)

Underwater vehicle sections in huge submerged cave networks.

"More color."

maybe have a scenario/horde mode going on, like annex or submission while a hord is after your team,
also, i would like it if you can move while they do the tally at the end of each horde

also, GeOW3 needs a beta to avoid this shit again

I want Marcus to turn into a ninja, and ride a unicorn into the center of the planet, thus blowing up the world. Then he will float off and high-five a space hippo.

I would also love to see huge large scale battles with many COG and locust. Not sure if the 360 can handle it maybe GOW3 will be on next gen.

Frodo Baggins.

Needs moar sexy chocobo ass.

I'd like to see the shotgun make a return -- two-piecing everybody is a good way to let off some steam, and is a totally valid tactic.

um maybe something new in terms of gameplay. like really unique. 

-Smoke grenades need to be powered down/changed
-Chainsaws need to be lowered more quickly when under fire
-Lag issues need to be addressed
-Matchmaking needs to be within one's country (no more connections across the seas)
-Quitting needs to result in a time penalty, not a rank penalty (aka, if you quit you shouldn't be allowed to play for ten minutes)
-Perhaps an entire matchmaking revamp?  (aka, being able to specifically host a game type as in Gears 1)
-Stopping power of the lancer/hammerburst need to be lowered (slightly)
-The damage frequency of the ink grenade needs to be raised (slightly)
-The hammer of dawn needs (a bit) more ammo
-The boomshot needs to have only 2 grenades (not 3)
-The weapons on Day One need to not rotate (this may have been fixed in the update)
-Submission needs some kind of revamp (it's very frustrating, not very fun)

As for new things I want in Gears 3?

-More playable characters in multiplayer (aka Anya)
-One or two new weapons (aka some sort of hammer of dawn-ish weapon that is quicker but less powerful)
-New multiplayer maps (obviously)
-Some sort of upgrade system for multiplayer (even if it's just cosmetic upgrades, it adds playablity - this one won't happen though because Cliffy has already stated that he wants people to play the game for the fun of it, not to grind up levels for upgrades or something like that)
-Some sort of blood mount riding action
-More corny/campy humor
-Some emotional content in regards to Anya
-More of a role for Anya

I want it to be like Gears 2 but just a bit better and you know, like new levels and new characters and new weapons and awesome crazy shit like that.
