^Yeah, Python at Efteling has them too. I really like them so I'm really glad Paris has decided to get them for Space. Maybe we'll see them added to R'n'R if get good enough feedback from guests.
I reckon it's best not to have spoilers for the new night-time show but I've been browsing and found some great images and notes on a few details. It sounds like it's going to be EPIC, like, some of the effects are just going to be amazing and totally unexpected and magical.
Oh they've also announced that there will be a special 20th anniversary menu at some of the restaurants (the more expensive ones) and they come with an added option of a special viewing area for the show. We're still awaiting more details on that though.
There have been quite a lot of changes happening on main street and a few announcements here and there. For example the main street station is going to be completely covered in gold leaf for the anniversary.
