Disney launched a new preview site.

A couple of things here. First: RSS will top out at 40 MPH... 25 less than Test Track. Not all together surprising, as it is a "family" attraction, but I was hoping it would hit a higher speed.
Second: Confirmation that there will be NO MATER whatsoever in Mater's Junkyard Jamboree. Instead, it will feature a "giant jukebox that [Mater] personally built from his prized possessions!" (The ! is there's, not mine, mine would look like this :mean
You can just make out the jukebox in the concept art below.
Ironically enough, Disney is still trying to sell the notion that Mater will be present by prominently featuring a concept art of Mater in the middle of the Jamboree (even though the official description confirms that he won't be).
That is all.
