Well, since I went today and have information from today, I'll make a few comments here.
First, every rollercoaster ran one train except Superman and Mine Train. The park barely had enough people in it to fill each train, and it was a fair policy due to the rain that fell all day. Batman and GASM almost needed two, but it wasn't any more than a 15 minute wait for either (for any seat other than the front).
The one exception here was Goliath. It sorely needed two trains, considering that, according to the station counters, it was releasing a whopping, amazing, astounding, ELEVEN trains per hour. The line was on the stairs or in the station all day, but it would take about 20 minutes to get on any row, and about 45 to an hour for the front. I am horribly spoiled by how fantastic the Nitro Crew was three weeks ago, but the lackluster operations by the employees there were enough to get comments from the general public.
Park employees were very slow everywhere, uncomparably worse than GADV a few weeks ago, but it was ok this time due to the emptiness of the park. I could easily see myself getting pissed off if the park had double the people of today, which would have been easy. Very slow ops. Superman's quickest dispatch was 3.5 minutes by my watch.
Also, GASM in the 6th row was RIDICULOUSLY rough. The worst ride I have ever taken on any coaster ever, worse than Son Of Beast, Mean Streak, GA Cyclone, Twisted Twins or anything else a million times over. If you ride GASM this year, get OUT of the wheel seat (last row in any car). I would rather have been punched in the face by Floyd Mayweather.
