Tragically it is mostly only moderate Republicans who are going to lose seats. Most of the current tea party candidates are being rewarded for this. It is the non tea party candidates who are getting the flak. Either a third party is going to come out, or tea party is going to lose a bunch of seats by fielding uber conservatives in right leaning districts. I think he latter will happen in 2014 and 2016 and the former will occur after 2016 elections. Depending on who is the Republican presidential candidate. If it is Christie, Tea Party will leave the GOP to form its own party. If its Cruz, traditional Repubs will form a third party.
