Well, to be honest, i would love to see Stone Cold wrestle full time again but that ain't gonna happen. In all those full time wrestling years Austin suffered knee injuries and a neck one. At this moment, his knees are in terrible condition unfortunately and it seems like he never healed 100% from the neck injury in 1997.
So, even if i want to see him again wrestle, it's preferable to stay inactive because with another knee or neck injury doctors has said that he might be paralysed and in a wheelchair and i don't think there is any true Steve Austin fan that would like to see that.

Now, as far as special appearences, guest referees and maybe a Wrestlemania match(as its speculated), it would be good to see him wrestle one more time, if he is able to. Personally, i'd love to see Austin as a General Manager again, he is very entertaining!

WA: As for The Miz, he has shown improvement in his time on the WWE, but i don't think he deserves something much better than what he gets. I am not really a big fan of him..
