If you click on the links on the N-numbers in the wiki you can see some of the flights the aircraft are scheduled on (for now)... see if they line up with your upcoming flights. I imagine as that list grows it won't be an ideal way to determine if your flight will have one of the new aircraft
You can also use flightstats.com and look at the event timeline on the day of your flight to see what tail number gets assigned to your flight. Compare to the list in the wiki and see if you won the raffle
N525AS -- 10/0?/16
