It's important to understand the legislative system in DC and most all people do not. In order to overturn existing law, which the ACA is, is a much different process than introducing a new law. This is simply an initial process to begin the revision and to send legislation to the Senate. The "real" legislation will occur in the senate and they will then conference with the House. 
For people to raise Cain, based upon their reading and listening to the uniformed press, requires the Congress and administration to get the work out about the process. Just hang in there and make your decision AFTER the bill is passed by Congress, which may be next year. Until then it is simply a waste of one's energy to predict what will be in the final bill.
