For those that don't have snapchat here's the answers you might be looking for:
There is going to be a new coke stand going between the whizzer entrance/exit.
Most rides have new generic spiels. Eagle also now has a warning saying "ride is now starting." (I was stuck today)
Aunt Martha's is now Strutters, it will offer chicken sandwiches and nuggets. Original, spicy, and grilled. The enclosed dining area next to whizzer has also been removed. No more shade for you. The front windows of that building haven been replaced.
Oasis is still there next to Justice League but it has been torn apart. Counter included.
The pathway between Demon and River Rocker is closed during Justice League construction.
Since the last image shown by SFGAm's snapchat, the brick pathway between oasis and demon has been removed.
Fling and Triple play will be down for some time.
King Chaos is also down, X Flight has 1 train and so does Goliath....for now
Pictorium will have something new in front of it'so entrance. Ground was torn up in front of it. Possible repaving but there were no issues like cracks there last year.
Eagle's station is being scraped of its paint to prepare for prime/paint. No red side yet.
Panda Express is now Chop Six like the other parks.
Capacity wise, I was fairly impressed with the attendants speed this year compared to previous years. There were some worse than others (particularly flats) but let's see how they handle the opening weekend crowds.
Feel free to discuss these changes in the 2016 minor updates thread.
