Yes, content providers still like to sell their content in packages. So to chose flex, you need to be flexible. If you are absolutely wedded to some specific set of channels, then they'll get you. My guess is that after a few months, most people will barely notice whether they have 30 channels or 200. But then, other people will barely notice the price difference between 30 channels and 200 so, there are different options for different people.
To save $10 a month [now $12], DISH recently let subscribers drop locals. Save $144 a year if you have an antenna. And, you will get all prime channels uncompressed and all the sub channels that DISH does not carry.
