I am a casual TNA fan, but I've been watching this angle and I really want it to be good. I want WWE to have competition and, if TNA proves to be that, all the better to them. I think the 'they' angle will cement whethere they can be legitimate competition to the WWE powerhouse or not. Well, at least the 'they' storyline will tell me if I want to tune into TNA when it's on, or just watch it OnDemand.
In terms of 'they', after reading reports, I have a strong feeling it could be AAA, so a TNA-style Invasion angle. In terms of gaining viewers in South America, I think it could be a good idea. However, a lot of casual fans haven't really heard of AAA, so I think it could end up being disappointing. If they want it to bring in names who are well known, former WWE stars such as Helms and Carlito would be good, but if they want to expand the business and possible fanbase, teaming up with AAA and doing and Invasion-style concept would work. Really, it all depends on how TNA want to handle this.
Personally, I'm not a fan of 'they' being Dixie's parents; it'd be a huge disapointment to me. I mean, if you've been planning an angle for months, hyping it and acting as if it's the biggest thing in wrestling, I really don't think the owners coming on screen is the best option. TNA is a wrestling show; if Bob and Janice were involved in the Deception angle, fine, but please TNA, you don't need more management types, especially not in the 'they' angle. Unless it's Paul Heyman in a management role, which it won't be.
Knowing TNA though, I can see it being Dixie's parents. Here's hoping to it being a lot better than that.
