If the deal was signed, then TNA wouldn't be releasing a statement, they'd be releasing their lawyers to prevent these guys from appearing in WWE.
Styles said they had a deal in place, but TNA took too damn long to get things finalized and then WWE came in with a much bigger offer.
Aries is a good get for NXT, but they should let him know that shoving his dick in a Divas face gets him more than a slap on the wrist here.
