In a suiting turn of events, the first new Zoid announced at Stand River is the Shield Liger Marking Plus Ver.! Shield Liger was also the first HMM Zoid to be announced, and according to Koto's website, it hasn't been rereleased since the launch of the series in 2006. From first glance it looks like the MPV might be a slightly darker, richer blue, closer to the original Tomy motorized kit, but this is hard to confirm with photos alone.
