It's most likely a branding change, Dreamworld Facebook has said that "all will be revealed soon." So I see the new rebrand being rolled out on the 26th Dec. (Also, when I replied with "I look forward to everything coming on the 26th of December then;" DW then replied "Fun times ahead for all. :)" - not that it necessarily means anything towards the Q4U upgrade/rebrand)
I went back there today with a different camera and got the photos below.
I personally, having been to various U.S. parks, I don't find either of them scary in the slightest.
There are three variations of the system; Bronze, Silver and Gold. (Below is copied straight off the sign)
Bronze: Virtually places you in the queue while you continue to explore the park. (Equal to the current wait time)
Silver: Virtually places you half way in the current queue wait time. (Up to 50% Faster)
Gold: Ride Express Gold Riders, please simply head straight to selected ride. (Up to 90% Faster)
Disclaimer: Wait times are an approximate and subject to change.
The Restaurant looks pretty decent.
Sorry, the above photo doesn't show much, but oh well.
I thought I'd include the above one either way, it isn't the best, and the lighting didn't help, but it gives a little bit of a glimpse inside the Motorsport Experience.
There is the Milk carton container things
I tried taking a picture of the visible part of the train, but my camera wasn't good enough; but it's still attached below anyway...
