Though nothing is certain until a show is actually announced, there are a number of assumptions we can very safely make about a CGI Muppet Babies production:
* No-one will feel any obligation to cast either the classic Muppet performers or the original voice artists from Muppet Babies in the new show. Odds on, they'll get a bunch of professionals who we've never heard of, but who are all based in the one place. Simpler and cheaper that way.
* No-one will feel any obligation to replicate the exact character line-up of the previous show. The target audience for this kind of show will be toddlers and young children who probably won't remember the earlier series. Even if that kind of audience does get accustomed to repeats, they're less fussy than us fan types.
* We shouldn't assume that the central conceit of the previous series -- long excursions into the babies' imaginations -- will be maintained. All that film integration work would make the show more expensive, so it could well have more conventional storylines. (This is more of a speculation than the other two points.)
One of the factors that makes a new MB series likely is that kids who grew up watching the show are now parents themselves. Lots of other 80s cartoon series have experienced a revival, so MB is definitely a possibility. But most parents will have little more than a vague nostalgic memory which might make them more likely to push their own offspring in the direction of the new MB. And as for us obsessives? We'll watch the show regardless of how it changes, so why worry too much about us?
