According to the Wrestling Observer Newsletter, WWE placed a hold on the 2300 Arena (the old ECW Arena) in Philadephia to run NXT live events on 5/15 and 5/16. However, nothing was confirmed and a local MMA promotion seems to have swooped in and reserved the space for 5/15. There’s no news yet on whether WWE still has plans to host a show the second day.

Ring of Honor will be running the same venue just two days prior.

I think they'll show up there and hate the place.
