You are all assuming that Yamato will get the toy licence for M25. As far as I know, it's still not been decided or announced yet. From what I understand, the major sponsor has first rights of refusal.
We could well end up with a situation where Bandai get the licence and then sit on it and do nothing, just to stop Yamato making money. Worst case scenario, but it could happen, given that Bandai has never really cared about or put much effort into Macross merchandising.
