I don't think Worlds of Starcraft will ever happen. I've been getting the impression that Starcraft 2 will be much like what Warcraft III was over Warcraft II. I have Warcraft II sitting in my drawer, and when you play it it feels like something out of 1995, but along came Warcraft III centuries later and improved it in every way.

That's what Starcraft 2 needs to be like. However I won't even touch it if they don't have UMS in it. Melee just wasn't my thing.
