Ok I've spent a few minutes going through the alltheanime catalogue on their site and these appear to be the Blu-ray titles with Collectors editions that they have in stock, I've added a note for the ones I think are very unlikely to be in the mystery box.
We can rule out the following because they've already been on offer.
tokyo esp
Space Dandy complete
Sword Art Online 2
Samurai Flamenco part 1
Fate/kaleid liner Prisma Illya
and taking into account the following
There will be a mixture of offers on already released titles and pre-orders for upcoming releases.
Any offer for an already released title will have a set amount of units available - this will be made clear in the listing itself - on a first come first served basis.
*DELIVERY OF ORDERS AS PART OF THIS PROMOTION*
Please allow up to 72 hours (excluding weekends) from when you place an order as part of our 12 Days of Christmas Promotion for dispatch. You will receive notification when it has been shipped.
NOTE 1: If you include products in your order they will likely be shipped separately.
NOTE 2: Pre-order products will be dispatched in time for day of release (or sooner if possible)
We know some of you may want to try and budget for these offers, so we thought we'd give you a little helping hand. If you were wanting to partake in every single offer we have over the 12 days, if you're wanting to purchase Blu-rays you would be spending a total of £405.00*, and if you're wanting DVD you'd be spending £120*. On average you're saving 50% of retail price across the board.
(*May be subject to change, but certainly won't be more than that.)
There will be no title on offer that will have been released after April 2016 - though this may not be the case for any promotions during this time that may be a bundle style offer, such as the mystery box offer on day 12 (read about that below)
NOTE - The final offer of our 12 Days of Christmas promotion is the Ltd Collector's Edition Mystery Box offer!
By purchasing this you will receive 5 Ltd Collector's Edition sets that we (Anime Limited) have released. You DO NOT get to choose which sets you will receive.
There is a set list of titles that will be included in each box - titles DO NOT differ between each Ltd Collector's Edition Mystery box purchased.
A title has been selected by each member of the Anime Limited team, making that 5 titles that will be included.
NOTE - Some of the Collector's Edition sets included will have Blu-ray and DVD discs, some will be Blu-ray only.
possibles from what I can see based on them having collectors/limited editions and still having stock.

Aldnoah.Zero Season (unlikley due to release date and cost)
Assassination Classroom Season 1 Part 1 (unlikley due to release date and cost)
Blood Lad - Collector's Blu-Ray Set
Expelled From Paradise - Blu-ray+DVD Ltd Collector's Edition (unlikely due to release date)
Fuse memoirs of the hunter girl
Gankutsuou - The Count Of Monte Cristo
Giovanni's Island (seems very unlikely due to RRP of the ultimate set)
HAL - Collector's Edition Combi-pack
Kill La Kill (there are 3 collectors sets, although it seems very unlikely to me)
Lord Marksman
Lucky Star (seems very unlikely)
Miss Hokusai - Ultimate Edition Blu-ray/DVD (seems very unlikely)
Noein: To Your Other Self - Blu-ray Limited Collector's Edition (the manga DVD set of this didn't do well from memory)
Patema Inverted - Collector's Edition
Ping Pong The Animation - Blu-ray/DVD Collector's Edition (unlikely due to release date and rrp)
Psychic School Wars - Blu-ray/DVD Ltd. Collector's Edition (unlikely due to release date)
Wings Of Honneamise - Collector's Edition DVD/Blu-ray
I'm tempted to give it a punt, but I've already got several of the films and pretty much expect Wings or Patema to be in the bundle.
[edit]
I'm an idiot, I've gone for it on the basis that there is enough there I haven't got that even just getting two items not already in my collection would probably pay for the box (and any duplicates will likely go to a good home).
