Hate to dis-agree with Jim on that point, but I do.
There's a subtlety in the look that really helps define a character. I think may puppeteers would agree (and has been stated in many MANY books on the subject)... the look of a puppet really sets the tone for their personality.
In my opinion, the "new" Fozzie is laid out to be a buffoon... like he was in Muppet Treasure Island. I think that character got stuck on Fozzie. He's been steadily losing intellectual power since then.
I prefer Fozzie to be a bad comedian, not an idiot. You can be a lovable failure without being stupid. And the changes in his look have followed (or perhaps preceeded) each lessening of his acumen.
But that's just my opinion.
As for the removal of the armature, I'm sure that it'll probably be a loose armature of wire inside... one deft seam opening in the back, a little stuffing removal, pull the wire out, and voila! Sure, there'll be clean-up work, like finishing off the arm hole and sewing on a sleeve or what-have-you. But I don't imagine it would be anything too earth shattering.
