Capcom isn't the only company that is doing this unforunately.
My view of it is that DLC's should be extra content that is not done prior to release or whole new content created after release. If the content is done enough to be included on the disk at launch then it should be availible then and there, end of story.
I unforunatly have yet to learn my lesson as i've just purchesed RE: Op Raccoon City in hopes that its a fun ass game. While i havne't heard of any DLC debacles it is still very early. But in all if i don't get really into he game tonight i'm just taking it back tomorrow and getting SH: Downpour instead, heh.
