I'm already far more excited about that show than about Wrestlemania itself.
It'd also be a good way to set NXT performers up for a Raw debut 3 days later, if they decide that they want to bring up any of the current NXT wrestlers on the post-Wrestlemania Raw.
Hopefully a great NXT show will inspire the main roster performers to put their all into their matches too, even if the bookers likely won't put them in much of a position to succeed.
Good decision, in my mind. If this is close to as good as the Brooklyn show, I'll be very pleased.
