On which platform do you've the most friends to play with?
Do you want to wait a month longer on dlc or not?
Maybe these 2 questions can help you out.

Myself will get it for xbox because I only own that.

Ill be buying it on both systems.

I will get it on the XBOX 360.

1. Its always better on Xbox 360

2. All my friends will be playing it

3. I dont have a PS3

As it stands, I'm planning to pick up the Hardened Edition for Xbox 360 and Standard Edition for PlayStation 3 on day one.

Follow me on twitter.

Me, personally, the only reason Im getting it for Ps3 is because I only have a Ps3, not an Xbox 360. There is no difference between Mw3 for Ps3 or Mw3 for Xbox.

(Ps3 is better than Xbox )

I'll get it for PS3 because it's the only current-gen console I have.

I preordered ps3 Hardened. No Doubt mw3 is going to be a great game, even if it is a LOT like mw2. Though I do agree, its a shame to see how much CoD favors XboX. Ps3 is a WAY better console, better graphics, better controller, everything. XBox's pay network isnt any less laggy than ps3's free one either, but yet they still favor xbox. If I end up paying for Elite it will ONLY be if IW stops this favoring the XboX bs and gives ALL its paying customers DLC at the same time, and ALL of the same content. The XboX even gets extra things for preordering hardened edition, Ps3 does not! how friggin lame is that??? We Just got Treyarch'd.

Xbox 360. Why? Because Im getting the limited edition xbox. I like my FPS games to be niiiiice and Xbox-y.

Truth of it all, I prefer the xbox controller for FPS games.

360 because:

Bigger gaming community

DLC seems to come out earlier or exclusively only on it

Already paying for the XBL so might as well get use out of it

Lastly, still don't trust PSN after all that crap with their security this past year

Xbox 360 becaaaaauuuuuse:

1. It's my primary gaming platform

2. Has the biggest online community (including 95% of my friends)

3. Controller is 10^1000x better than the dualshock 3

4. Earlier DLC

5. Xbox > PS3
6. Trollolol

I'm going with XBOX 360 due to me having one. Luckily I believe that the game is more now created for XBOX 360. The specs on it look, play, and feel better than on a 360 than a PS3. At COD XP what did everyone get to play MW3 on? XBOX 360... I also love the 360 > PS3 due to the fact that XBOX Live is far more superior than PS3 Online....

Xbox 360 because I own it.

I will be getting it for PS3. This is because I only own a PS3. I like owning a reliable console. I had 4 360s RROD on me so I swapped to PS3 and never looked back. Now if I had both consoles I would definitely get MW3 for 360 due to getting content first. MW3 and Gears would be the only games I would play on it.
