Perhaps Sazabi would follow the path of Nu, a titanium release in December (one year after normal release).

Its done to coincide with nightingale, back to back release to boost sales.

Hi nu is not very detailed (at least by new ver ka standards anyway). Clearly this is not because they cant do it as evident by nu n sazabi, my guess is that bandai already had in mind for ppl to pose nightingale and hi nu together and they dont want 1 kit to completely out class the other in terms of aesthetics to avoid looking out of place. With that in mind, it isnt too far fetch to suggest that bandai had planned all along to release both kit back to back to boost sales n maximizing profit off of fans of Beltorchika's Children and or Amuro/Char fanbois.

As for why its not tandem nov/dec instead of aug/sept that we do not know. With 2 new gundam anime airing soon one of them could be made into dec kit, or it could be an even more ridiculously big n expensive kit yet to be announce. We will know soon enough.

Indeed!
we already have sinanju & nu ver ka titanium so far .

dun forget the unicorn too

am i the only one that thinks the unicorn titanium finish is crap? somehow the "titanium" finish doesnt really come out compared to the nu ver ka or even sinanju red titanium.

AFAIK the only differences between OVA and ver ka unicorn is the head vulcans and the added knee bend
The head vulcans i dont really care for since they're neglectably small
Extra knee bend? FAU isnt going to do more than just standing there
Sinanju had the bazooka.. what would FAU get? Take out the beam javelin? (Remember he never used the javelin in the show IIRC)

I can't make my mg master gundam pose the one leg fighting style..The back pack too heavy

By any chance that the 1/100 Full Armor Unicorn Gundam would be release in OVA version since the Sinanju and the Unicorn was release in ver KA and followed with the release in the OVA version?

saw this posted by time machine
what does gloss injection version means ? glossy finish like titanium ke ? 

hmn....cant really tell from the pics....still looks like regular to me except the shoulder pads red looks nicer than regular

The paint is not solid, it is glossy. Which means it reflects light better. Just google gloss-coated gunpla and compare it to the popular flat-coated gunpla (the same kit) for comparison.
