So, we have a preview set from 2011 Rittenhouse Archives release on file here...
https://www.tcdb.com/ViewSet.cfm/sid/203832/2001-Rittenhouse-Xena-Preview-Set
...and I see that we also have one added (probably incorrectly) under season 4&5 that is called "UK Preview Card set" here...
https://www.tcdb.com/Checklist.cfm/sid/189896/2001-Rittenhouse-Xena-Seasons-4-&-5---UK-Preview-Card-Set
...so, should that be moved outside like the separate release of US preview set, right?
Furthermore, I've seen Australian preview set from 2001 as well which looks like this...
https://tvmoviecards.com/products/xena-seasons-4-and-5-australian-preview-card-set-au1-au6
...so that should be a third one listed separately, right?
We have those preview sets outside of base release since we don't group put them under Promo sets (at least we didn't on any other example I stumbled upon and this is the first time I've seen preview sets added to some set's promo sets which can be seen here...
https://www.tcdb.com/Inserts.cfm/sid/82179/2001-Rittenhouse-Xena-Seasons-4-&-5
...note that "Preview Set" there is duplicate of set we have outside (probably because Rittenhouse releases those preview sets separately in limited numbers and earlier than base sets).
But I find it strange that there are UK or Australian preview sets out there... and that they're released by Rittenhouse... but if there are like it appears to be, we should have them all outside, right? If someone tells me all those sets should be treated as Included sets for Xena Season 5&6 base set then that will just force me to submit tons of IRs to move all such preview sets into other base sets, so I hope that is not the case :P
