I was there last Sunday, Monday, and Tuesday (19-21) and the wait times were pretty bad. As usual it depends heavily on the time of day you are looking at. Mornings were great, but by midday I was seeing some crazy waits. Like you I saw Nemo go up to something like 75 minutes. I wanted to yell at all the people in line "it's not worth it!"
At least to me it wouldn't be.
IASW is a strange one, it would go from practically no wait at all up to an hour wait then back to no wait quickly. I suppose like others say it has to do with parades going on in the area.
Space, Indy, Star Tours, Matterhorn regularly had hour waits or longer, Space usually around 90 minutes. Pirates surprised me, typically that line moves quickly enough that it doesn't build too much, but people were lined up around the corner and up onto the bridge. Splash Mountain had very long lines all day long, but that's to be expected for a wet ride in summer.
Jungle Cruise had typical posted wait times of 20-30 minutes, but it looked much longer than that...I saw areas of the queue on the upper level open that I didn't even know could be used as queue sections!
Even when it poured rain for a few hours the crowds didn't seem to die down. I would definitely say it was the busiest I have seen the parks. No other events in the area were going on to increase crowds that I know of. BUT, do not fear, it was still a fun trip and we still rode lots of stuff. We just made sure to ride the busy things in the mornings, first thing, and then mostly rest in the afternoon (which was needed anyway since it was hot and humid). And if you care at all about characters, the wait times for those didn't seem bad at all.
