This is not going to happen anytime soon. WWE is lossing money and ratings as it is so with them already losing money as it is why would they buy something that is having more problems as themselfs. It is kind of like adding weight to a sinking ship.
There is a difference between losing money and losing profit. The "E" is far from being in the hole money wise. Wrestlemania just had over 1 million PPV buys do the match and thats around 60 mil dollars in one show just from PPV. Thats not including merchandise, sponsorship, or ticket sales. To say they are "losing money" either shows you have no idea what you are talking about or that you honestly misquoted your source. The simple fact of the matter is that TNA doesnt have a profit base big enough for the "E" to even consider a purchase at this point, and if they did I still cant see Vince taking it on right now. TNA is no threat what-so-ever to WWE because they are not even on on the same night. There is no competition there. For anyone to say there is isnt thinking clearly. TNA tried to go head to head with RAW and failed miserably, and moved back to Thursday to save face, and their ratings are still dropping. Vince isnt interested and i don't see any type of move from him at all to start negotiations for a purchase. If Panda comes to him and puts an offer on the table, them maybe (big MAYBE) Vince will consider.
