We know for sure BFG is a go this Sunday night, but there has been an update on "who" helped fund the advance shows. 

Apparently according to The New York Post, some "unidentified third party" paid for the advance shows. TNA President Billy Corgan also had commented on the pay-per-view proceeding this Sunday as well.

"It's a go, as far as I've been told," Corgan has said. 

Nothing as of now has changed as far as ownership goes of TNA.  The Post noted that "WWE and Corgan are expected to resume talks about a change in Impact ownership after the weekend's broadcast."
