Don't forget about the whole Muppets Ahoy! show--with Victor and Drew on that cruise the From The Balcony segments may be hindered.
Of course, with Vic & Drew working a different kind of show, I can't see why not to bring back Steve and Dave. However, I had heard other people performing the characters when I was in Los Angeles and I'm game if they could step up.
Still, Jim Henson thought enough of his puppeteers to hire them and I don't want to see their jobs gone--I dunno. I want to see some new shows and the characters in their peak performances again. The closest by far has been the VMX film on NBC a few years back and I'm afraid Diz is going to stick The Muppets with a stereotype that they are only good for Holiday shows and films, or parodies of other stories.
I want to see The Muppets doing what they do best--being themselves!!
