I'm trying to think, and outside of Punk (actually more a Indy Circuit fame) who spent little time in TNA, and Kharma, there haven't been many TNA 'stars' that have made the jump to the WWE. And I know contracts have expired here and there for the "E" to pick up some of TNA higher tier talent. I listened to an interview with James Storm and he was talking about how he would never say never, and when the offer was out there that HHH was interested in Beer Money, both men decided to stay loyal to TNA and resign with them. Plus he mentioned the WWE would have ended up splitting them after a few months (like TNA did anyways), and he didn't want any of that.
So my question is; "Is the WWE just not interested in TNA talent, or is it that TNA talent are too loyal or don't want to be ruined by WWE the reason we don't see any TNA talent in the WWE?"
