Spike TV indicated Wednesday that there have been talks of maintaining Impact Wrestling as a live program on Thursday nights once its scheduled run concludes at the end of the summer. If no commitment is made, TNA will resume taping the program on a bi-weekly basis.
In my opinion they will only benefit in the long run by keeping it live. The product has really shined since they went live and if they keep it up the product can slowly start to expand and develop into something greater.
