You probably read it in the newsletter or my site since it is posted on the season two episode list page:

It was a quote from April's Sci Fi Magazine article which I will repost here:

<font color="orange">The first two episodes, a two-parter, deal with Jeremiah, who has been caught by the [military from Valhalla Sector] and reunited with his dad, whom he was looking for all of last season. And our other characters who have been caught with him, they're all kind of stuck in the box. The question, of course, is how are they going to get out of that box when there's almost no support out there for them tactically? They only people running around loose are Lee Chen, who has questionable loyalties, and Kurdy, who is kind of on the zone. And where we eventually end up is in a massive conflict between Thunder Mountain, and the forces there, and Valhalla Sector.
There's actually a way that I found to bring down Valhalla Sector that's probably the creepiest, unsettling, meanest thing I've ever done in writing. I won't tell you what it is yet because you have to have the shock value there. [It will be] chilling. </font color>
I don't think JMS would let out a huge spoiler in an interview like this. He is usually pretty careful about those kind of things. In fact, the interviewer even said that he was careful to reveal any S2 information.
Anyway, I do agree that it is a spoiler but it isn't not a huge one. A better analogy would be to say to someone who just started watching B5, "The forces of light win the Shadow War." Yup, that is a spoiler, but you don't know any details and there are still some pretty major whammies that are not apparent in that statement.
Besides, this show is about -hope- and VS is just about the opposite of that. Did you really think they were going to triumph?
We still don't know how it is going down or what the consequences will be either. It could even be a temporary set back for all we know. I see it as more of JMS fucking with our heads than a huge spoiler.
The other thing I found interesting in the article is that JMS also said that he has had the puzzle pieces in place since the first episode!
