Well it's all around the news sites, but I get at what you're saying. Thing is, it's the best for both worlds. Cornell goes on with his solo career like he has planned and RATM finally reunite. It would be the perfect win-win.
This really sucks. I liked Rage, I liked Audioslave. I guess I can cherish their three records, and I'll check out Cornell's solo album, although this is a bummer to hear.
