I'm going to join with the minority of internet fans and say "I really hope both guys stay.", as I really like both guys.
No offense to anyone here, but how many of us have run a successful wrestling promotion? We've all heard of the dreaded backstage politics, and we know the major parties involved in this kind of business. Gunn & Holly aren't those kind of people, so we have to assume their work in the ring is what has kept them their lasting jobs.
Billy is a very talented guy that can put on great matches and get the fans into it. Like it or not, the guy is more popular than Chris Benoit was before he got the title. Gunn is easily one of the greatest tag team wrestlers of all time.
Hardcore Holly is extremely unpopular with the TPWW crew, yet he is in the same category as Gunn in the marks' eyes. He gets better reactions than Rob Van Dam at times. Holly is not a brilliant tactician, but he's a much more realistic worker than most other guys, and he gets the fans into it. Wrestling is not what it was originally intended to be, and is now more entertainment than sport. Holly fits that role well if he is given a part to play.

if they are on they're way out,

if they stay,

if they are used to make the product better overall.
