its sold out. 
No it's not. It's not even on sale yet. These are just pre-orders from 1 re-seller. Why not buy directly from Baikal when they open up their order book? It will cost you less.

I tried to get a pre-sale order for 2 devices, and answer from Baikal is
Hi，
Thank you for your contacting.
I am sorry the Giant-B is currently out of stock. Any updates on stock we will let you know by making announcement on facebook/twitter. You can also pay some attention on our website.
so i really don't understand how Baikal company can sell devices that are not produced yet, furthermore, when there is no cost announced!
i would need some help to understand, all these bad communication points are bad for Baikal.
