DLC or not the game is incredible. i've only played two of their games...Oblivion and Fallout 3 (both on the PS3) and both are incredibly awesome games. so why wouldn't i check their work out in the future? trust me...the DLC will come eventually.
they were with Microsoft first (like Namco or Square were with Sony) so of course they're going to show some love to the people that helped make them who they are today.
