If you notice on the ticket, the FP is simply bordered on the top in yellow with "TEST TRACK" written on the top. A face lift for the ride may very well change the name on the FP ticket, meaning that these passes may already be 'retired.' I believe the new ride will also utilize the FP system. We will see during the 2012-2013 holiday season what they will decide on for the fate of this fast pass ticket.
This is nothing new. We've seen fast pass updates before. A refurbishment may be a good excuse to update the logo on a classic ride. Here is an example of Disneyland's California Screamin FP that got an update as well between 2009 and 2010. The back of the ticket now has the FASTPASS logo with Donald Duck. Before that, fast passes had quite a bit of logistical information on the back.
Star Tours at Disneyland now has a blue logo printed on the top versus the old-style monochromatic gray.
Not only have they evolved because of a change in the name of the ride or an update to the logo on the front, the back of the pass is just as important in determining if a ride will receive an updated fast pass. You can see here how the old FP used to look like on the back (left), when they have been now updated to the new FASTPASS & Donald Duck logo (right).
Test Track isn't the only FP equipped ride undergoing a face lift. At WDW, Big Thunder Railroad is also experiencing a temporary closure (between January 9 and May 28, 2012). The difference between this refurb and TT is that TT will probably end up being an entirely new ride and concept whereas Big Thunder Railroad is experiencing some updates to their ride station and attraction features. I do not foresee a change to the current FP ticket. Other FP equipped rides at DL, DCA, and WDW will be experiencing additional closures. Be aware that if you are collecting FP to find out the next regularly scheduled closing and to get the passes before major refurbs are in place. You never know if it will change the design of the fast passes.
