After months of silence the Zoids MSS site has announced a temporary pause in the line. During this pause the series will be rebuilt, and hopefully will be returning with more kits in the future. Salamander, which was previously being worked on has also been put on hold and will not be released, presumeably until the line continues. Below is a translation of the notice posted on their website.
(Notice of the end of the first series MSS Zoids)
We thank everyone for your patronage with the MSS Zoids, but the end of Zoid's 30th anniversary has come and we're bringing the current lineup of the first series to a close. As for the new products, including the already announced commercial product the Salamander, sales will be paused. While they're paused the products will be overhauled and the series will be reconstructed. We apologize for the very late notice. We sincerely hope that you continue to patronize our company's goods in the future.
