I like the way you think.
I went and watched that part, and I'm not absolutely certain that it's as cut and dried as that. He could have meant generally "I look forward to reading in the press (in the future) what Commissioner Silver is saying" [about the idea of expansion].
I'm also not sure about inferring the fact that it's Seattle who would be getting an expansion team. It depends on how literally you think he meant the word "your" in the term "your newspaper." (Although I certainly agree with everyone who thinks it would be ridiculous to move our team and give us an expansion team.)
I think more than anything, Stern and his law degree are being very, very careful about how he words things (as usual). If you notice, he actually reframes the reporter's question first so that it isn't as direct, so that he doesn't have to provide a direct answer. He's very careful to say "it was not discussed," rather than answer the actual question, which is more along the lines of "would expansion be considered?"
Having said all of that, I strongly, strongly hope you're absolutely right.
I agree, I don't think it's a slam dunk or anything, but it's a very strange way to word a generic "maybe at some point we would consider expansion to a strong market." He also could have said "I look forward to reading about Commissioner Silver's thoughts on this issue in the future." The fact that he went out of his way to indicate that Seattle would have something to write about in the Silver era is curious at the least. Maybe all it says is that that's the way Stern himself is leaning (which would also be a good thing).
Or maybe I spent too many hours as a kid reading theories about Lost, and my irrelevant-details sense is out of control here.
