Having Steiner in TNA was a step in the right direction[star power-wise].
Having Steiner & Jarrett as a team

. Having Steiner & Jarrett interrupt every match even bigger
I like the idea of TNA kinda stealing the Hell In a Cell thing by putting a top on the "Six Sides of Steel" match. Having weapons to grab from the roof is cool too.
TNA has been gradually progressing. Not that we have to guess, but, I'm thinking Goldberg is Sting's big surprize. That would be good for star-power and recognition from the casual wrestling fan, but, could be bad if Goldberg injures an up-and-coming new TNA talent[Daniels, Styles, Alex Shelley, etc].
If done right, Goldberg coming to TNA could be the catalyst for others to start jumping over from WWE. Now if TNA could only get a 2-hour timeslot.....
