The following listing has appeared on Hobby Link Japan's website this week. It lists the details for a Bandai 1/12 scale Clone Trooper kit which will be released in June 2016.
The kit will include helmet options to build either the phase 1 or phase 2 trooper. It will also come with a display base and swap out hand options. Two weapons will be included. The description doesn't mention any additional parts such as pauldron's and kama's but we can hope they may be included.
Sadly, the kit is not going to be directly available to either the UK or US. In fact if you search for this listing on their .com website you will find nothing - you can only see it HERE on their .jp.com site. This is of course down to their licencing agreement only allowing these kits to be sold in Japan.
The list price of 2203 Yen equated to about £14.20 but expect to pay £20-£25 to import these.
