Several months back, there was talk in TNA of turning the Global title into a hardcore title. However, it's very possible that those plans, if there were any to begin with, have been scrapped as I've read and heard nothing else about it.
I'm not all that wild about hardcore wrestling quite honestly. Hardcore wrestling, to me, is something of a novelty to drag out every once in a while but it gets stale really fast on a regular basis. I was never all that hot about a hardcore title in the WWE and that was especially when the 24/7 rule was initiated. The WWE Hardcore Championship changed hands more times than any other major pro wrestling title in wrestling history and that did nothing but completely discredit an already questionable title situation to begin with.
Also, hardcore wrestling is an example of why we've had so many wrestling tragedies. The Chris Benoit story has made a lot of people both in and out of wrestling, both fans and people involved within the business, take a different look at hardcore wrestling. Benoit was someone that competed in his share of hardcore matches in his time. In the wake of Benoit, I find it hard to believe that any company could claim to legitimately care about its wrestlers and consistently put them in ultraviolent matches.
As for yet another reason, TNA already has enough meaningless titles on their roster as it is. Most of the titles they already have don't get used properly, so a hardcore title would probably just add to the problem. The Knockout titles, both singles and tag team, are pretty much worthless, the tag team titles are at their lowest ebb in the history of their existence, the Global title is absolute crap and the X-Division title has started to gain a tiny bit of steam and momentum but has a long way to go. The only title in TNA that's been used well has been the world title.
