Well, you could wait. But in the meantime, you could put in a temporary stand in until the release of the revised and better version.
For myself, if Yamato does decide to re-do the YF-19, then the two standard versions I have will be made into altenate color schemes, ala VF-19A (VF-X "Ravens") and VF-19A (Macross the Ride). Either way, it's a win-win situation.
