My first reaction: I see why WWE did this, as I was expecting it to happen earlier (particularly, at NXT TakeOver: Respect). While we can't say for sure if this is a good idea or a bad one until we've seen it happen and some of the repercussions, I do think it could end up being a positive in the long run. Samoa Joe could be a great opponent for Finn Balor to overcome where he could believably defeat Balor at any time, so the fans will be invested in their title matches. Also, Baron Corbin was pretty much the only heel at the top of NXT now that Tyler Breeze is leaving and going to the main roster, so someone needed to fill that spot. Joe fits that spot better than pretty much anyone else who could be in the main event, so I'm down for this change.
