Just seen on Warlord games site (www.warlordgames.co.uk) via TMP that they are going to do plastic 28mm ECW and TYW as well as supporting metal figures as well. They are going to do boxes of 36 (12 pike & 24 shot) and they have some very nice pics of a few of the figures up on the site with more promised over the next few weeks.
They even look useful for converting to the later Dutch wars and even the LOA.
Great news.
