Just noticed today that Forbidden Planet have amended their ETA for Star Wars Black Series Wave 7 up to 30th March (previously April)
Wave 7 contains Bossk and Han Stormtrooper and a March release, albeit the end of March, feels more in line with what we have seen previously in terms of new waves hitting eBay in the Far East, then the US and then UK shores
Star Action Figures, the other UK site with pre-orders listed for week 7, are quoting April.
The Deluxe Tauntaun remains listed as a May 17th release date.
Pre-orders for Wave 7 in the UK can so far be found at Forbidden Planet, Star Action Figures and Forbidden Planet International
