Goodbye TechTV hosts

It looks like not only is Silicon Spin and John Dvorak gone form TechTV, but Kate Botello, co-host of Extended Play, is also departing as of April 1. Her final episode is running now through the weekend, as well as the fifth of April. Geez, so many things are changing. The two stations I watch on a very regular basis are CNN and TechTV and both are going through major post Easter changes. Is there some correlation? Anyone know? Thanks.
