I just wonder if it's a temporary recast or what. I'm liking Peter's Elmo. It needs some more practice (he sounds like he's just a bit older), sounding just a little like earlier Elmo (ever notice when they recast these guys they always sound like they first did?)... but I think that brings up a good point about Walter. Seems we'd wind up seeing less of one of them. And since Elmo's a freaking one monster dynasty, chances are, it's Walter we'll go without. I still wonder what John's sounded like.
We won't know for sure until season 45, though. Or at least a public appearance.
In all honestly, it wouldn't surprise me if it was temporary. I'd think Universal wanted some recording specific to what they needed and so Sesame needed to get someone to voice Elmo fast, hence casting Peter. But if Peter is in fact the new Elmo, yay for him because he certainly deserves that. And if it is in fact the case, I don't think we'd lose too much of Peter's other characters. Remember, right in the midst of his performing years, Kevin was bouncing between New York doing
Sesame and
Dog City, Los Angeles doing
Dinosaurs, doing Clifford for Muppet stuff whenever they needed him, plus going to London to do
Muppet Treasure Island within that 3-4 year period. The only reason he stopped doing Muppet productions was because he was getting so involved creatively with
Sesame, something I doubt Peter will get into. But then again, this is all just speculation.
