It is completely inexcusable. And the excuses they have given so far, are ridiculous, because they add to the problem which they are presenting as the reason for not releasing DLC in the first place.
I hope my business really takes off so I can get rich and then show these idiots how it is done.
edit:
I guess they mean paid DLC and not free add ons. I guess that sorta makes sense. PC gamers traditionally don't want to pay for DLC anyway, so releasing it would be pointless, since that DLC would be pirated anyway, even by legit buyers of the game.
I've pirated a bit of DLC, I will admit, and it is for games I've bought. It is purely because I am just not used to being nickled and dimed for my games on the PC. I am probably wrong to do so, but I can sorta understand when a developer decides not to go for PC DLC.
Just won't be viable, when PC gamers were going to be the smallest percentage to pay for the game anyway, and then when even a tinier percentage of that small percentage would have paid for the DLC.
On the flip side, you could argue that it wouldn't require a giant effort to release the DLC, and they might as well do it for free a few months after the console versionsm just to buy some goodwill.
