Larry Sabato gives final predictions:

Before Labor Day we issued a projection of +47 net gains for the Republicans. ... Even at this late date, we see no need to do anything but tweak the total R gains, based on more complete information now available to all. Thus, we are raising the total to +55 net R seats. We consider 47 to be in the ballpark still, but more of a floor than a ceiling.

He also forecasts an 8 seat Republican gain in the Senate. It's a big wave.
