It looks like there could possibly be another Superstar Shakeup sometime after SummerSlam this year.
The Wrestling Observer Newsletter has confirmed recent rumors that there is talk within company about making roster moves this fall and several ideas are being discussed. The belief is that after there first shakeup, there were less interesting rosters and this could be a chance for the company to make up for that.
There has also been talk about possibly moving one or more Superstars from the main roster to NXT during the shakeup. These Superstars would be ones that Vince McMahon simply isn’t going to push even if they are over, or individuals who are doing nothing on the main roster but could potently be useful on the NXT brand.
