Just got back as well, it is really awesome in there. You are right Merf the Globe is directly in front of you as you exit, it is not fully circular as it is jutting out of a wall. Behind that wall is where the Cities of the Future exhibit will be located. The globe is very cool and looks to be the same as the Movie Balls over at Universal for the night show. It says at one point Coming Soon a Re-imagined Spaceship Earth (or something like that) it gave me chills and then it shows the shadow of a girl who is exploring her possible futures and they hint at certain things that may be in the new ride such as future cities, future cars and future medical techniques. hmmmm sounds similar to the post show.
As for the post show offerings, I can see issues once Epcot gets busier as they will be very popular and there are not a lot of kiosks. I did manage to try the Super Driver and it was fun, not great, but fun. They have multiple languages to choose from and then you basically become a 007 type character that must stop a evil spy. You have 5 minutes to race across a future landscape that includes cites, snow and, countryside using Seimens technolgy that will be available for cars in the future. How fast you complete your mission = your score/ranking. I am not good at video games and I got the top ranking so its pretty easy.
The Medical one was too busy to do, but all that were experiencing it seemed really into it. The look of the whole room reminds me of a cross between Space Mountains first few que rooms and old style Epcot, its a great atmosphere. It looks a lot larger than the old Global Nieghborhood (spelling??) and I believe all the screens above just showed the stars moving.
All in all it was very nice and exciting to see, oh and on the ride as you came out of the descent tunnel tonight was something I have never seen before, a wet paint sign just taped with blue tape onto the wall that surrounds the windows looking into the post show room. Looks like they were busy last night.
