The official UK release date for Star Wars Legion Clone Wars is 19th September 2019. The date has been confirmed by the sole UK distributor, that all UK retailers purchase from, and so far the date appears to be holding with no news of any delays.
A limited number of the Clone Wars sets were available for special purchase at GenCon 2019 (the largest tabletop-game convention in North America by both attendance and number of events) at the beginning of August. The fact that the sets were available at GenCon in August bodes well for an on time release.
So a few lucky people already have these, but the rest of us have to wait until September.
As always, we will ship these the day before the release date, so that they will arrive with customers on release day.
