Naturally it is all educated guesses in terms of rides but Nintendoland will have 3 rides. The Donkey Kong Coaster will be a coaster and Yoshi will be a traditional dark ride (possibly with a Buzz Lightyear shooting influences). Mario Kart will probably be a hybrid. Not total racing Test Track but not Fast and Furious either. I expect you to be moving on a real track.
On the opposite side of the park (rumored How to Train your Dragon) you can see in concept art one big coaster right above the land as well as a smaller one inside the land. hard to tell specific others but just because lets split the difference and say 1 screen based dragon flying ride and one Dumbo type ride.
Harry Potter Land v3 is where things get tougher. The Show building looks massive and who knows if it will be used for one ride or multiple rides or a huge indoor exploration section with a ride. If I had to put money down it I would say the land would be Mexico Pavilion from EPCOT style. A really nicely themed outside but inside would be the majority of the shops and eating and rides. Diagon Alley has survived with one ride so I am sure the new land could as well but since Universal has free reign I will guess 2 rides. All HP rides have had real movements and props in addition to screens so I would guess things would remain the same here.
Back on other side of the park Universal Monsters land is the big maybe. With the success of the Universals Monsters house at
HHN I would not say no to a expanded walkthrough experience like Walking Dead has in Hollywood. There is also rumors of a Universal Monsters dark ride. And then there is the show stage in that area as well. This is really the wild card area.
Then finally as mentioned there is a Coaster outside any specific lands. That brings the possibilities of more rides outside a specific land as well. Looking at the concept art there is a area perfectly shaped for a carousel and other buildings with footprints that seem to big just for a shop or restaurant.
So I am not to worried about a over abundance of screen rides for the new park.
