Well, They have the 18" gun Turret in 1/200 and now they also released a bridge:

I guess if we wait we can build the ship from parts as they piecemeal them out.
I recall earlier this year seeing a substantiated report that a 1/200 kit of Yamato wil be coming out-soon. However, I can no longer find that link.
Another post I was involved in stated: "Kitted by Wave (same Japanese company that released 1/200 Mikasa)..., moulded by Trumpeter ..."
Maybe released for Christmas?
