The game sold well, is still played a fair bit and it seemed to be the perfect game for DLC but no DLC. 
DICE were even saying before and during release how they were looking into DLC but no DLC. 
The maps are already there, they just need to alter them some and add the frostbite engine but no DLC.
 
Can you think of why they didnt release any DLC? 
Too busy working on BC2 and unannounced games? 
They didnt think theyd be able to compete with other big FPS shooter games? 
The game didnt do aswell as expected and so they didnt think it was worth the money/ resources? 
 
Could somebody with some more insight into this kind of stuff take a stab at why?

working on bad company 2. i get the impression that BF1943 was just for a quick pay check.

1943 seemed more like an experiment. There are plenty of Battlefield maps that could have been converted into DLC, but I think EA just wanted to test the waters with a downloadable game on this scale. I was a little disappointed that the game was never supported, but then again it was only $15 and I played the hell out of the game. Well worth it either way.

Surely it wouldn't of required that many dudes to make 1-2 maps though? "

I just bought it a couple of days ago (since it is on sell this week) and it feels great for how cheap the game is, I know I haven't put a huge amount of time into it yet but I don't really feel like it needs anything else like DLC, feels good with what it has right now.

I think if they at least released some more maps it would be awesome. Some of the achievements are hard to get for it though!

I wouldn't be surprised if we saw another type of game of the 1943 scale.
 
Here are my predictions for DICE:
 
March: Bad Company 2 releases, supported by Day 1 DLC.
May: Map-pack for Bad Company 2 releases. Most likely paid, or for people who are VIPs. (bought the game new)
Late-summer: More maps, maybe a game-mode for BC2.
Early 2011: New arcade game announced for the summer, I would like to assume Battlefield 1943: Europe, with 5 European maps, and more diverse classes.
Fall 2011: Battlefield 3 is released
Summer 2012: A $20 Arcade game is released, either Vietnam or 2143.
Fall 2012: Bad Company 3 releases against MW3.
 
 
 
 
 
 
 
Yup, most of that was bullshit, but it is probable bullshit.
