Just got an email saying "a title you were waitlisted for will be available in Swaps" for Thursday. I rarely used the Waitlist feature (since I assumed it didn't work), so I'm a bit curious as to what flagged it. The swap preview isn't live yet, although there is an announcement that the third Thursday of every month will now be the day ROTMs and swaps drop going forward, so December wasn't a holiday-related on-off.
Off the top of my head, I recall waitlisting Monk's Palo Alto (which I eventually picked up during a TBT drop) and Method Man's Tical. Will be curious to see if either ends up in swaps this go-round.
