The motivation for the merger is that comcast wants it's channel G4 to reach a larger viewing audience. This can alrady be shown by all the people that have tech tv and no G4. For the people that don't know G4 was a channel created to try and cash in on the 11 billion dollar gaming industry, unfourtunately the channel does not reach many people, hence the merger. To my knowledge nothing has been announced about which shows will be staying or leaving, but in my beliefs at least The Screensavers will be safe, for it is Tech TV's powerhouse show. Sadly shows like the tech of, or interesting shows like "Body Hits" or the new "Let 'er Rip" (which coincidentaly will be having an hour long special on FIRST robotics this thursday may 13th at 9 pm eastern) will get the axe. Hopefuly Comcast will be kind to the fans of Tech TV, but in my heart i feel that it is not likely.
(i feel really sad now that i realize whats happening to one of my favorite channels...i'm so sad)
