I have to admit, when Kevin Rose started talking about bringing back the "old" Tech TV after Comcast completely destroyed it, I didn’t think it was possible. After all, studios cost money, crews cost money, and they had no sponsors and no ad programs. Well, bit-by-bit the new "Tech TV" is taking shape.
Kevin Rose has his Systm show, Yoshi has From The Shadows, and Leo Laporte, Patrick Norton, and the rest are all contributing to This Week in Tech. Kevin Rose is even moving back to San Francisco where "We hope to have our new studio built out by mid-August allowing us to hit our full production stride and cranking out episodes on an almost weekly basis."
To succeed, the new "Tech TV" will have to find an economic model that works, unlike any traditional TV station. It should be interesting to see how it goes 
Good luck guys!
UPDATE: Kevin Rose’s new studio is called Revision3. Here’s the Wikipedia entry.
