As noted, TNA scrapped the planned April set of Impact tapings at Universal Studios, and it’s likely they will be announcing the tapings for May instead.
The Universal Studios website is advertising Impact tapings at Soundstage 20 from May 8th-May 11th. These tapings should carry Impact all the way up to the Slammiversary PPV, which as of now, is the only TNA PPV other than Bound for Glory which will be on regular PPV this year.
