I normally only watch the NHL and the Tour de France on Versus, so I haven't noticed any change. I might watch their MLS coverage. I always found the picture to be pretty good, especially compared to our RSN's (CSN Mid-Atlantic), so I have no comment there.
One thing I noted that is kind of cheesy but that I kind of liked anyway was that when the channel was called Versus, they put their logo in the middle of the score box graphic so it would read, for example, "New York [VS] Washington" where "[VS] denotes their logo of that circle with "VS" in it. Hardly a big deal, of course, just a nice little touch.
The change they could make that I'd like would be to get rid of Emrick and Milbury on their NHL broadcasts. Emrick's style and voice simply irk me; he's not a bad announcer per se, but even my wife said "this guy sounds constipated" during last Monday's game. His constant groans make it sound like he's trying to squeeze out a dump. Milbury just goes out of his way to be an arsehole and then gets angry when any of the other guys MIGHT be seen as disagreeing with him.
