PC for me. Played F3 on it and had no problems.

Probably PS3. 
 
 
Hopefully both 360 and PS3 versions are the same, because I prefer playing on my PS3

PC version for me.

I was going to preorder today for the PC, but Microsoft boasting that the first set of DLC is going to be Xbox-only soured it for me. I do own an Xbox, but I'd rather play it on PC for the mods and the better graphics. Still, I really enjoyed the DLC for Fallout 3. Now I dunno what to do, honestly.

I'll be getting it on the Xbox 360, then PC down the line.

PS3.  My 360 hard drive is at capacity and it is harder and harder to find stuff to delete off of it.  I could just buy a bigger drive but that being pretty much the cost of a new game or two I would rather just have the games.  Had I known before the day before the game comes out that the 360 was going to have exclusive DLC I probably would have got it for 360.  But since I ordered the game from Amazon and it is now too late to cancel my order I don't feel like buying the game twice and sending the PS3 copy back.

PS3.
 
Hopefully it wont crash as much as Fallout 3 did.

360 always. 

the 360.

PC all the way. I like that it's winning too.

the 360 of course

PC for the superior graphics and mods, and it's cheaper too!

The second you see Fallout 3 with a decent hi-res texture mod on the PC, there isn't even a question which platform New Vegas should be played on.
 
PC 4 life yo.

360 because I'm an achievement whore.

I'll still get it on PS3 regardless of this DLC announcement. I'm scraping the bottom of the money barrel as it is so I won't have enough money for add-ons anyway. 

I played Fallout 3 on PC and it was a lot better with all the mods and what not, but I like achievements and I'm still waiting for my new laptop to get sent here. I might get it again for PC somewhere down the road if I really enjoy it.

360, PS3 version will suck ass and PC gaming can fuck off in general.

Just hit 20 on Fallout 3 on the PC. Just pre-ordered New Vegas the other day so now I don't have any money to buy Broken Steel to up the level cap, so I'm going to have to wait till Friday to get New Vegas to sate my Fallout lust.  

PC for mods and, well, it's a PC...

PS3 all the way.

360, and PC down the road.

Played FO3 on 360, looking forward to high resolutions and mods in my NV pc version! 

I platinumed the first one and I'll platinum this one too

PC - only real way to go. 
 
People are really hatin' on the PS3.

I was going to pick up the xbox version but then I went here 
http://www.fallout3nexus.com/
and realized what a mistake that would be.

PC for me, and I wouldnt worry about that DLC for the 360, it will be out for the PC too eventually.  =)

360

PC for me.  Those $10 are precious. 

PEEEEEEEE 
CEEEEEEEEEE 
 
looks better.

Probably on my 360.

not even sure i am going to be picking it up with all the games coming out in the nest 6 weeks but it will be for the 360 if i do. 

Xbox360. I want me some achievements and be able to play on my 40 inch screen :D

It's simply unfathomable to me why the amount of people playing this game on the Xbox is neck to neck with the amount of PC players. Why on earth would anyone pass up on the opportunity to download a mod that gives everyone in the game fantastic looking beards, wield a GAU-8 Avenger cannon spewing 30mm uranium tipped "party mix" rounds ripped from an A-10 Warthog, or play as a Spess Mehrine from the Adeptus Astartes (or from one of the traitor legions, World Eater's ftw) just for ACHIEVEMENT POINTS?

The personal confusor. Crazy mod support and better graphics plus mouse/keyboard controls. The only way I could imagine playing it.

PC, can't risk it on the consoles with FO3's apparently game breaking glitches in the past.

None. Between this and Vanquish, I'm going Vanquish. Besides, I got a lot of games to catch up on, so a shorter game is good.

Mainly PC for me. I will eventually get the 360 version when the price goes down though . . .

Is there any advantage to the ps3 version? I generally prefer my ps3 but with the xbox version getting the dlc first, it seems like 360 is the way to go.
 
Does the ps3 have significantly faster load times or anything like that, what with the data install?

PC all the way. Can't imagine a Fallout world devoid of mods. If you don't have 15 buggy, messy, game-breaking mods, you're not playing Fallout to the fullest.

360.

PC
 - free mods
 - community bug fixes
 - console commands
 
Plus my PS3 is occupied by Castlevania:LoS atm
