I don't know as I'd call it a "revival"--sure, the game has had its ups and downs, but the game and the hobby in general have been going strong ever since its creation. The fact that GEN CON has been increasing in attendance every year is proof of that, I think.
I do like the fact that other RPGs are mentioned in the article, such as Achtung! Cthuhlu. There it is for anyone who's interested.
