In an interview with Fan Pass, ex-Pantera vocalist Phil Anselmo spoke about the possibilities of a reunion and what exactly it would take, including a serious, in-person discussion with ex-drummer Vinnie Abbott. He states that there is “…no doubt…” in his mind that Black Label Society guitarist Zakk Wylde would be the best person to replace “Dimebag” Darrell Abbott.

What it would take to get it off the ground:

But at the end of the day, there would have to be a meeting at a table — or without a table — between Rex [Brown], Vince and I, and there would have to be a bigtime understanding between the two of us before anything happens at all.

If the reunion were to happen, Anselmo states:

If there was ever a proper presentation, like, OK, PANTERA is back together, Zakk’s on guitar, that would be a massive feeling. That would be outrageous. And I would go to war. I would be in the best shape possible.

I hope to hell they don't. Pantera was a good band and they had some great songs, but rarely does anything good come out of these reunions and crap. 9/10 any new music they release is just awful with shades of what made them good..
